[AZ-666] [AZ-673] [AZ-648] ignored set + UDS VLM + mission FSM batch 5

AZ-666 mapobjects_store:
- internal/ignored.rs (HashSet<(mgrs, class_group)> for O(1) suppression)
- internal/passes.rs (per-region PassTracker with observed-id set and
  end-of-pass removed-candidate sweep)
- Classification::Ignored wired into classify; apply_decline +
  is_ignored + pass_start + end_of_pass on MapObjectsStoreHandle
- new tests/ignored_and_sweep.rs (3 AC + 2 supplementary)

AZ-673 vlm_client:
- internal/peer_cred.rs (Linux SO_PEERCRED via libc getsockopt;
  PeerCredOutcome::SkippedNonLinux on macOS dev hosts per
  description.md §8)
- internal/prompt.rs (pre-send ROI size + format + prompt
  non-emptiness validation)
- internal/wire.rs (length-prefixed JSON envelope with base64 ROI)
- internal/uds_client.rs (tokio UnixStream client; bounded
  reconnect; hard-stop on peer-cred mismatch; per-request deadline)
- VlmClient with both eager (open/connect) and lazy (new) ctor
- workspace Cargo.toml: base64 + libc as workspace deps

AZ-648 mission_executor:
- internal/types.rs (Variant, MissionState, TransitionKey,
  Telemetry, TransitionEvent, StepOutcome)
- internal/driver.rs (MissionDriver trait + DriverError +
  DriverAction)
- internal/fsm.rs (variant-agnostic Transition + FsmCore + step_one
  with per-transition retry budget keyed by TransitionKey)
- internal/multirotor.rs + internal/fixed_wing.rs (typed transition
  tables; multirotor has Armed/TakeOff, fixed-wing parks in
  WaitAuto for operator AUTO)
- public API: MissionExecutor::run spawns the FSM task and returns
  a clone-safe MissionExecutorHandle (state, health, subscribe,
  paused_reason, retry_count)
- new tests/state_machine.rs (AC-1..AC-4 via ScriptedDriver fake;
  SITL conformance lands with AZ-649 telemetry forwarding)

Workspace: cargo fmt + clippy -D warnings clean; full
cargo test --workspace --all-features green (1 ignored = AZ-665
perf gate). Tasks moved todo/ → done/, autodev state set to batch
6 selection.

+//! AC-1 / AC-2 — happy-path multirotor / fixed-wing flow with a fake
+//! driver. The driver stands in for the SITL conformance target; the
+//! state graph and event publication are what the AC asserts.
+//!
+//! AC-3 — bounded retry on mission-upload rejection: first attempt
+//! rejected, second succeeds, FSM proceeds.
+//!
+//! AC-4 — cap exhaustion: all 3 default attempts rejected → FSM pauses,
+//! health → red, transition event published, no transition past
+//! `MissionUploaded`.
