npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 6c2d26e884 fix(managed-agents): add generation counter to ReadinessClaim to prevent stale-claim mutations
A preempted ReadinessClaim had no ownership identity: after
force_claim_in_progress() seized the latch from a flush-owned
InProgress, the flush's in-flight barrier could still call
complete()/drop and unconditionally mutate the latch. Two legs:

- Leg 1 (same-scope case): stale flush barrier finishes, calls
  resolve()+mark_ready() → latch certified Ready while reconcile
  was still retaining rows → stale rows publish unarbitrated.
- Leg 2: stale barrier errors → RAII drop resets force-claim's
  InProgress to Unready mid-migration → next flush tick wins a
  fresh claim and certifies against mid-sequence state.
- Leg 3: run_boot_barrier_for_scope's abandon arm returned Ok(())
  which the enforcing wrapper treated as Success.

Fix: the latch carries a u64 generation counter. force_claim_in_progress
increments it; claim_in_progress records the current generation.
Latch mutations move onto the claim:

- claim.complete(db_path) → Ready only if latch generation matches.
- Drop → Unready only if generation matches.
- Preempted claims are silent no-ops in both paths.

BarrierOutcome enum added; abandon arm returns Abandoned (not
Success) so run_boot_barrier_enforcing never calls complete() for
an abandoned scope. mark_ready() and resolve() removed from the
public API; mark_unready() gated to #[cfg(test)] since all
production transitions now go through the claim.

Tests (g)/(h): stale complete/drop are no-ops after force-claim.
Test (i): leg-1 end-to-end interleaving — stale barrier complete
cannot certify Ready; rows retained after the stale complete
cannot publish until force-claim's own barrier passes.
Tests (c)/(e)/(f) updated to claim.complete() API.
