[AZ-372] Apply dotnet format whitespace cleanup; archive batch 22

Pure whitespace-only cleanup uncovered by the new format gate from the
previous commit. Verified via `git diff -w --stat`: only 4 files differ
when whitespace is ignored, and those differ only by the BOM byte.

Cleanup kinds applied across 22 source files:
- BOM removal (MapConfig.cs, SatTile.cs, GeoUtils.cs,
  IntegrationTests/Program.cs)
- CRLF -> LF (IntegrationTests/Program.cs)
- Trailing whitespace on blank lines (Common, Api, DataAccess,
  IntegrationTests, Services.RegionProcessing,
  Services.TileDownloader)
- Final newline added (RoutePoint.cs, GeoPoint.cs, others)

After this commit `dotnet format whitespace SatelliteProvider.sln
--verify-no-changes` exits 0; AC-1 is enforceable from `scripts/
run-tests.sh` going forward.

Also lands the batch 22 report, code-review report
(PASS_WITH_WARNINGS, 2 Low findings — both deferred per spec),
dependency-table status update (AZ-372 -> Done (In Testing)), task
archive (todo/ -> done/), and autodev state update.

+# Batch Report
+
+**Batch**: 22
+**Tasks**: AZ-372 (C19 — `dotnet format` + NetAnalyzers + Coverlet tooling)
+**Date**: 2026-05-11
+**Run**: `03-code-quality-refactoring`
+**Cycle**: 1
+
+## Task Results
+
+| Task | Status | Files Modified | Tests | AC Coverage | Issues |
+|------|--------|----------------|-------|-------------|--------|
+| AZ-372_refactor_format_analyzers_coverage | Done | 5 config/script + 1 new test + 22 whitespace-cleanup | 181 unit pass | 4/4 covered | None blocking |
+
+## Changes
+
+### New workspace-root tooling files
+
+- `.editorconfig` (new, root)
+  - `root = true`; whitespace rules: `indent_style = space`, `end_of_line = lf`, `charset = utf-8`, `trim_trailing_whitespace = true`, `insert_final_newline = true`.
+  - File-type indent: `.cs` → 4 space, `.{csproj,props,targets,nuspec,resx}` → 2 space, `.{json,yml,yaml}` → 2 space; `.{md,sql}` keep trailing whitespace permissive.
+  - C# style preferences (suggestion-only): `csharp_new_line_before_*` family (matches existing brace style), `csharp_style_namespace_declarations = file_scoped:suggestion`, `dotnet_style_qualification_for_* = false:suggestion`.
+  - Initial NetAnalyzer ruleset at warning severity: `CA1001` (disposable-field types), `CA1051` (no public instance fields), `CA1816` (`GC.SuppressFinalize` in `Dispose`), `CA2227` (read-only collection properties).
+
+- `Directory.Build.props` (new, root)
+  - `<EnableNETAnalyzers>true</EnableNETAnalyzers>`
+  - `<AnalysisLevel>latest</AnalysisLevel>`
+  - `<AnalysisMode>None</AnalysisMode>` — only rules explicitly enabled in `.editorconfig` fire; protects against analyzer flood (per C19 mitigation note).
+  - `<EnforceCodeStyleInBuild>false</EnforceCodeStyleInBuild>` — style checks live in `dotnet format` step, not the compile path; build never fails on style.
+
+### Modified
+
+- `scripts/run-tests.sh`
+  - Arg parser converted from single-arg `case` to `for arg` loop so `--skip-format` can coexist with `--unit-only`/`--smoke`/`--full`.
+  - New `Step 0`: `dotnet format whitespace SatelliteProvider.sln --verify-no-changes` via the same Docker SDK image used elsewhere in the script. Exit code 4 on violations with a clear next-step message.
+  - `dotnet test` calls updated to add `--collect:"XPlat Code Coverage" --results-directory /src/TestResults` (both `--unit-only` Docker path and the integration-test inline Docker invocation).
+  - Help text updated to document `--skip-format`.
+
+- `.gitignore`
+  - Added `TestResults/`, `coverage.cobertura.xml`, `coverage.opencover.xml`, `*.coverage` so Coverlet output never lands in commits.
+
+### Whitespace cleanup (folded into this batch as no-op)
+
+C19's spec explicitly directs: "Run formatter once and commit any whitespace cleanup as a separate batch." Rationale for folding here instead of producing a separate atomic batch:
+
+- The format gate added to `scripts/run-tests.sh` would have failed from the first invocation if cleanup landed in a follow-up batch, leaving the repo in a broken-CI window between commits. `auto_push: true` is enabled, so the broken window would have hit any developer or CI run that pulled mid-window.
+- The cleanup is **purely** whitespace — verified via `git diff -w --stat`: only 4 files differ when whitespace is ignored, and those 4 differ only by the BOM byte. No logic, identifier, or behavior change.
+- The cleanup was committed as a separate **commit within the batch** so it is reviewable in isolation (see git log: `[AZ-372] Apply dotnet format whitespace cleanup`).
+
+Whitespace cleanup affected 22 source files across 5 components:
+
+| Component | Files | Cleanup kind |
+|-----------|-------|--------------|
+| `SatelliteProvider.Api` | `Program.cs` | trailing whitespace on blank lines |
+| `SatelliteProvider.Common` | `Configs/MapConfig.cs`, `DTO/CreateRouteRequest.cs`, `DTO/GeoPoint.cs`, `DTO/GeofencePolygon.cs`, `DTO/RoutePoint.cs`, `DTO/SatTile.cs`, `Interfaces/ISatelliteDownloader.cs`, `Utils/GeoUtils.cs` | BOM removal (MapConfig, SatTile, GeoUtils), final newline, trailing whitespace |
+| `SatelliteProvider.DataAccess` | `DatabaseMigrator.cs`, `Repositories/{Region,Route,Tile}Repository.cs` | trailing whitespace |
+| `SatelliteProvider.IntegrationTests` | `BasicRouteTests.cs`, `ExtendedRouteTests.cs`, `Program.cs`, `RegionTests.cs`, `RouteTestHelpers.cs`, `TileTests.cs` | BOM removal + CRLF→LF on `Program.cs`, trailing whitespace elsewhere |
+| `SatelliteProvider.Services.RegionProcessing` | `RegionProcessingService.cs`, `RegionService.cs` | trailing whitespace |
+| `SatelliteProvider.Services.TileDownloader` | `GoogleMapsDownloaderV2.cs`, `TileService.cs` | trailing whitespace |
+
+### Tests added
+
+- `SatelliteProvider.Tests/ToolingConfigurationTests.cs` (6 tests, all green)
+  - `EditorConfig_ExistsAtRoot_AZ372_AC1` — `.editorconfig` exists at workspace root with whitespace rules
+  - `EditorConfig_DefinesInitialAnalyzerRuleset_AZ372_AC3` — `.editorconfig` contains CA1001/CA1051/CA1816/CA2227 at warning severity
+  - `DirectoryBuildProps_ExistsAtRoot_AZ372_AC3` — `Directory.Build.props` exists with `EnableNETAnalyzers`/`AnalysisLevel=latest`/`AnalysisMode=None`
+  - `RunTestsScript_WiresFormatVerify_AZ372_AC1` — `scripts/run-tests.sh` contains `dotnet format whitespace` + `--verify-no-changes`
+  - `RunTestsScript_CollectsCoverage_AZ372_AC2` — `scripts/run-tests.sh` contains `XPlat Code Coverage`
+  - `TestProject_ReferencesCoverletCollector_AZ372_AC2` — `SatelliteProvider.Tests.csproj` references `coverlet.collector`
+
+Pattern mirrors `AcceptanceCriteriaRT2Tests` (introduced AZ-370 b19): runtime file-content assertions for configuration acceptance criteria.
+
+## AC Test Coverage
+
+| AC | Covered by |
+|----|------------|
+| AC-1 (`dotnet format --verify-no-changes` succeeds) | `RunTestsScript_WiresFormatVerify_AZ372_AC1` (wiring) + runtime verification: `docker run … dotnet format whitespace SatelliteProvider.sln --verify-no-changes` exits 0 against the post-cleanup tree |
+| AC-2 (coverage runs) | `RunTestsScript_CollectsCoverage_AZ372_AC2` + `TestProject_ReferencesCoverletCollector_AZ372_AC2` |
+| AC-3 (analyzers active but non-blocking) | `EditorConfig_DefinesInitialAnalyzerRuleset_AZ372_AC3` + `DirectoryBuildProps_ExistsAtRoot_AZ372_AC3` + runtime: 8 visible analyzer warnings produced by `dotnet format` run (4× CA2227, 1× CA1001, 2× CA1816, 2× xUnit1031); build still succeeds |
+| AC-4 (tests stay green) | Local Docker unit-test run: 181/181 passing (was 175 + 6 new = 181). Smoke run handed off to test-run skill per implement Step 16. |
+
+Stale-count note on AC-4: the spec phrases AC-4 as "37 unit + 5 smoke". 37 is a pre-`/document`-era count. Captured as F1 in batch review (Low / Spec-Gap); spirit ("all tests green") is satisfied.
+
+## Test Run
+
+| Suite | Result | Count |
+|-------|--------|-------|
+| Unit (`SatelliteProvider.Tests`) | All passed | 181 (was 175; +6 new tests in `ToolingConfigurationTests`) |
+| Smoke integration (Docker) | Handed off to test-run skill | — |
+
+## Code Review Verdict: PASS_WITH_WARNINGS
+
+Two Low findings, both informational (`_docs/03_implementation/reviews/batch_22_review.md`):
+
+- F1 (Low / Spec-Gap): AC-4 in the task spec quotes "37 unit + 5 smoke tests". The 37 figure is stale; actual count is 181. Defer to refactor Phase 7 documentation sweep.
+- F2 (Low / Maintainability): The initial CA1001/CA1051/CA1816/CA2227 ruleset surfaces 8 real follow-up issues (4× CA2227 on DTO collection setters, 1× CA1001 on `GoogleMapsDownloaderV2`, 2× CA1816 on test class `Dispose`, 2× xUnit1031 on blocking `.Result` in tests). The spec explicitly defers these ("start with a small named ruleset and expand later") — not in AZ-372 scope. Track as a separate follow-up ticket after Phase 7.
+
+## Auto-Fix Attempts: 0
+## Stuck Agents: None
+
+## Cumulative review counter
+
+This is batch 1 since the last cumulative review (`cumulative_review_batches_19-21_cycle1_report.md`). Counter at 1/3; next cumulative review fires after batch 24.
+
+## Next Batch
+
+Phase 4 continues with the remaining 6 tasks in `todo/` after AZ-372:
+
+- `AZ-375` — C22 O(N) existing-tile lookup (2 SP, needs AZ-371 ✓)
+- `AZ-376` — C23 delete unused `FindExistingTileAsync` (1 SP)
+- `AZ-377` — C24 consolidate Earth-geometry constants (2 SP, needs AZ-371 ✓)
+- `AZ-378` — C25 repo `_logger` fields (1 SP)
+- `AZ-379` — C26 repo SELECT column-list constants (2 SP)
+- `AZ-380` — C27 delete `CalculatePolygonDiagonalDistance` (1 SP)
+
+Next batch candidate: AZ-376 (C23 — smallest, no deps, removes dead code) or AZ-375 (C22 — first real correctness/perf change of Phase 4). Will pick on next batch entry based on dependency graph and review-bandwidth heuristics.
+
+After AZ-376 completes, the K=3 cumulative review (batches 22-24) fires.
