Make recovery handoffs explain why a lane resumed instead of leaking control prose

Recent OMX dogfooding kept surfacing raw `[OMX_TMUX_INJECT]`
messages as lane results, which told operators that tmux reinjection
happened but not why or what lane/state it applied to. The lane-finished
persistence path now recognizes that control prose, stores structured
recovery metadata, and emits a human-meaningful fallback summary instead
of preserving the raw marker as the primary result.

Constraint: Keep the fix in the existing lane-finished metadata surface rather than inventing a new runtime channel
Rejected: Treat all reinjection prose as ordinary quality-floor mush | loses the recovery cause and target lane operators actually need
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Recovery classification is heuristic; extend the parser only when new operator phrasing shows up in real dogfood evidence
Tested: cargo fmt --all --check
Tested: cargo clippy --workspace --all-targets -- -D warnings
Tested: cargo test --workspace
Tested: LSP diagnostics on rust/crates/tools/src/lib.rs (0 errors)
Tested: Architect review (APPROVE)
Not-tested: Additional reinjection phrasings beyond the currently observed `[OMX_TMUX_INJECT]` / current-mode-state variants

 62. **Worker state file surface not implemented** — **done (verified 2026-04-12):** current `main` already wires `emit_state_file(worker)` into the worker transition path in `rust/crates/runtime/src/worker_boot.rs`, atomically writes `.claw/worker-state.json`, and exposes the documented reader surface through `claw state` / `claw state --output-format json` in `rust/crates/rusty-claude-cli/src/main.rs`. Fresh proof exists in `runtime` regression `emit_state_file_writes_worker_status_on_transition`, the end-to-end `tools` regression `recovery_loop_state_file_reflects_transitions`, and direct CLI parsing coverage for `state` / `state --output-format json`.

 63. **Droid session completion semantics broken: code arrives after "status: completed"** — dogfooded 2026-04-12. Ultraclaw droid sessions (use-droid via acpx) report `session.status: completed` before file writes are fully flushed/synced to the working tree. Discovered +410 lines of "late-arriving" droid output that appeared after I had already assessed 8 sessions as "no code produced." This creates false-negative assessments and duplicate work. **Fix shape:** (a) droid agent should only report completion after explicit file-write confirmation (fsync or existence check); (b) or, claw-code should expose a `pending_writes` status that indicates "agent responded, disk flush pending"; (c) lane orchestrators should poll for file changes for N seconds after completion before final assessment. **Blocker:** none.

The event tells us *that* tmux reinjection happened, but not *why* (retry after failure? resume after idle? manual recovery?), *what state was preserved*, or *what the lane was trying to do*. **Fix shape:** recovery/reinject events should emit structured cause like: `resume_after_stop`, `retry_after_tool_failure`, `tmux_reinject_after_idle`, `manual_recovery` plus preserved state / target lane info.
