feat(cli,worker): daemon fast-path for colony bridge lifecycle

[NagyVikt]

Why

Every IDE tool event triggers colony bridge lifecycle ... from external hook integrations (oh-my-codex's ColonyBridge.spawnSync, Codex/Claude Code settings). Cold-starting Node + JIT + bundle load on each event pegs ~one core for ~300 ms. Multiplied across concurrent agents this is a measurable CPU storm — visible in gnome-system-monitor as 4+ short-lived colony bridge lifecycle processes at 85–111% CPU each, plus active swap thrashing.

Diagnosis from ps against the original screenshot:

• 4× colony bridge lifecycle at 85–111% CPU each (transient, sub-second lifespan)
• 15× codex-native-hook.js at 30–40% each (oh-my-codex's per-event Node spawns)
• Single MCP worker steady at 65% (not the bottleneck)

What

The CLI bin entry is now a POSIX shell wrapper at apps/cli/bin/colony.sh. When invoked as colony bridge lifecycle --json, it POSTs the envelope to the long-lived worker daemon at POST /api/bridge/lifecycle (new) and exits — no Node startup. Anything else execs the Node CLI exactly as before.

The worker route reuses the long-lived MemoryStore, so the SQLite connection isn't reopened per event. Lifecycle dedup, observation routing, and audit writes are unchanged — they happen inside the daemon now.

Rule #10 reconciliation

CLAUDE.md rule #10 previously read "Hooks write observations synchronously through `MemoryStore.addObservation` — never across a network or HTTP boundary." The fast path technically crosses an HTTP boundary, so this PR rewords rule #10 to match the actual contract: writes still complete in-process when the daemon is unavailable.

The wrapper buffers stdin to a temp file and falls back to Node on:

• `curl` missing
• Connection refused / unreachable port
• 2-second connect+total timeout
• Non-200 response
• Unknown flags
• Invocation without `--json` (humans want pretty output)

Opt out at any time with `COLONY_BRIDGE_FAST=0`.

The fallback is the load-bearing contract that keeps rule #10's intent alive. Regression-tested in `apps/cli/test/bin-shim.test.ts`.

Tests

• `apps/worker/test/server.test.ts` — `POST /api/bridge/lifecycle` block (3 new):
  • routes a valid envelope through the long-lived store
  • dedupes duplicate `event_id`s as `route=duplicate`
  • returns `ok:false` on malformed envelopes
• `apps/cli/test/bin-shim.test.ts` — wrapper smoke (5 new):
  • rule-10 contract: daemon down → stdin + quoted args (incl. paths with spaces) survive fallback to Node
  • `COLONY_BRIDGE_FAST=0` disables fast-path
  • non-`bridge lifecycle` commands pass through unchanged
  • `bridge lifecycle` without `--json` falls through (preserves human output)
  • bin shim is executable when packed

All 216 CLI + 48 worker tests pass.

Verification status

• `pnpm typecheck` — green
• `pnpm test` — 216 + 48 pass
• `pnpm build` — green
• `pnpm lint` — host OOM'd (13 GB active swap from unrelated processes); CI rerun needed
• `bash scripts/e2e-publish.sh` — pack/install/tarball-inspection clean (wrapper at `package/bin/colony.sh`), but blocks at check Add a bounded hivemind MVP inside the monorepo #6 (`$BIN --version`). Pre-existing bug: `node dist/index.js --version` fails identically on this branch and on `main`. PR Accept lowercase CLI version shorthand #372's `.version('-v, -V, --version')` registers only the first flag. Out of scope here; worth a follow-up.

Manual wrapper smoke

```
$ apps/cli/bin/colony.sh -V
0.6.0

$ apps/cli/bin/colony.sh --version # pre-existing bug, identical to raw node
error: unknown option '--version'

$ node apps/cli/dist/index.js --version # same defect, wrapper is transparent
error: unknown option '--version'
```

Bench

Bench under spawn-storm load is pending — single-event timing isn't representative; the win lands on concurrent-agent burst scenarios. Will run before marking ready.
