[autodev] Update configuration and documentation for cycle-1

- Enhanced `.env.example` with detailed CMake build flags and replay-mode strategy flags for development and CI environments.
- Updated `.gitignore` to include a new deploy rollback bookmark.
- Revised `_docs/_autodev_state.md` to reflect the current task status and steps.
- Added new lessons to `_docs/LESSONS.md` regarding testing and architectural improvements.
- Documented changes in `_docs/02_document/deployment/ci_cd_pipeline.md` to reflect the relaxed OpenCV version pin.
- Updated test data documentation in `_docs/02_document/tests/test-data.md` to clarify fixture usage and paths.

This commit continues the cycle-1 documentation sync and addresses various configuration updates for improved clarity and functionality.

+**Re-validation result (2026-05-19, greenfield Step 14 Phase 1)**:
+`pip-audit` against the `.venv` returned `opencv-python==4.11.0.86`
+with `"vulns": []` — neither PyPI's advisory feed nor OSV.dev has a
+published advisory tying CVE-2025-53644 to the 4.11.0.86 pin band.
+The 4.x-line supported branch appears to have absorbed the relevant
+patch in 4.11.0.86. Runtime evidence: NFT-SEC-04 (which feeds
+`cve-jpeg-fixture` to every OpenCV imread/imdecode path under
+AddressSanitizer) is the executable confirmation in the test suite.
+The leftover remains OPEN because the upstream constraint (gtsam
+4.2 → numpy<2) has not changed, but the CVE-2025-53644 exposure
+window has effectively closed at the current pin. Replay condition
+unchanged: numpy-2-compatible gtsam (or alternate SE(3) backend).
+See `_docs/05_security/dependency_scan.md` for the full scan output.

+also lift the `requires-python = ">=3.10,<3.12"` cap that currently
+masks the exposure.

 ## Replay procedure
 
 1. Confirm a `gtsam` package with numpy-2 wheels is on PyPI **or** swap
