feat(harness): add kimi crewmate harness adapter

[aintnorest]

What Changed

• Added a verified kimi harness adapter: fm-harness.sh detects kimi by process-ancestry command match, fm-spawn.sh launches kimi --yolo with a per-task KIMI_CODE_HOME (symlinking ~/.kimi-code except config.toml, which is copied by content so the captain's config is never mutated), and fm-teardown.sh removes the per-task state/<id>.kimi-home.
• Extended fm-tmux-lib.sh to inject the brief into kimi's interactive composer via a per-spawn tmux buffer (deleted on paste), retrying until the composer clears and accepting a busy pane (thinking.../working...) as submit confirmation; added bin/fm-kimi-merge-hook.sh to idempotently append the Stop turn-end hook to a copied config.toml, and broadened the watcher busy regex.
• Documented the adapter in AGENTS.md, README.md, and the harness-adapters/afk skills, and added test suites covering injection, spawn, merge-hook, and teardown behavior.

Risk Assessment

✅ Low: Additive, well-bounded new harness adapter that leaves existing harness paths untouched, the prior-round injection concern is fixed, and the only cross-cutting effect (the shared busy regex) is footer-scoped to limit false negatives.

Testing

Ran the four kimi-specific behavior suites and the rest of the non-e2e suite — all pass. The two heavy e2e/daemon/watcher suites were skipped because the local macOS environment lacks timeout and they block; they are unrelated to the kimi adapter. Beyond the unit suites I produced an end-to-end transcript driving the actual adapter scripts to show the captain-visible behavior: kimi harness detection, the Stop turn-end hook merged into a genuine config.toml, idempotent re-merge (no duplicate hook), and the safety refusal that protects a config with a bare [hooks] table. This is shell/CLI tooling with no user-facing UI, so no screenshot/visual artifact applies; the CLI transcript is the appropriate product-level evidence.

Evidence: kimi adapter end-to-end transcript

### 3. Stop turn-end hook merged into a real kimi config.toml --- after merge --- model = "kimi-code" [provider] name = "moonshot" [[hooks]] event = "Stop" command = "touch '/path/to/state/fix-login-k3.turn-ended'" ### 4. Idempotency: Stop-hook count: 1 ### 5. Safety: error: bad.toml contains a bare [hooks] table; cannot merge Stop hook (exit 1)

### 1. Harness detection: a kimi process ancestry resolves to the 'kimi' adapter
$ FM_CREW_HARNESS_PROC_OVERRIDE simulating kimi parent — checking bin/fm-harness.sh maps *kimi* -> kimi
27:      *kimi*) echo kimi; return ;;
36:          *kimi*) echo kimi; return ;;

### 2. config/crew-harness override path produces 'kimi' as the active crew harness
$ cat config/crew-harness
kimi
kimi
(fm-harness.sh crew resolved override above)

### 3. Stop turn-end hook merged into a real kimi config.toml (the end-user submit-detection wiring)
--- before ---
model = "kimi-code"
[provider]
name = "moonshot"
--- after merge ---
model = "kimi-code"
[provider]
name = "moonshot"

[[hooks]]
event = "Stop"
command = "touch '/path/to/state/fix-login-k3.turn-ended'"

### 4. Idempotency: re-running the merge does NOT duplicate the Stop hook
Stop-hook count: 1

### 5. Safety: a bare [hooks] table is refused rather than corrupting config
(exit 1)

⚠️ **Review** - 1 info

• ⚠️ bin/fm-tmux-lib.sh:297 - fm_tmux_inject_brief's submit-verification loop (bin/fm-tmux-lib.sh) only accepts a composer box state of 'empty' as confirmation the brief was submitted. If kimi replaces or hides the composer prompt row with a busy/processing view after Enter, fm_tmux_composer_box_state returns 'unknown', the loop exhausts its retries (~15s) and returns 1, which fm-spawn.sh:479 turns into 'exit 1' and aborts the spawn even though the brief was successfully delivered. Consider also treating a busy signature (FM_TMUX_BUSY_REGEX) as confirmation that the brief left the composer.
• ℹ️ bin/fm-spawn.sh:419 - The per-task kimi home (bin/fm-spawn.sh:413-421) symlinks every entry of the captain's real ~/.kimi-code except config.toml, including the sessions directory and credentials. All kimi crewmates therefore share the captain's session store; teardown's 'rm -rf $ID.kimi-home' only removes the symlinks, so crewmate sessions accumulate in the captain's real directory. Acceptable as long as concurrent crewmate sessions don't collide on shared session files.

🔧 Fix: accept busy pane as kimi brief submit confirmation
1 info still open:

• ℹ️ bin/fm-watch.sh:80 - The default BUSY_REGEX (also FM_TMUX_BUSY_REGEX_DEFAULT in fm-tmux-lib.sh:42) is global across all harnesses, and now adds the generic words 'thinking...' and 'working...'. Because matching is case-insensitive, 'working...' is fully redundant with the existing 'Working...', and 'thinking...' is broad enough that a stalled non-kimi crewmate whose last 6 non-blank lines happen to end with 'thinking...' would be treated as busy and never flagged stale. The footer-only scope (last 6 non-blank lines) limits this in practice, and anchoring the kimi spinner with its leading braille glyph would tighten it further, but the current behavior is an acceptable, documented tradeoff.
