fix(observer): replace hardcoded sleep 2 with PID file poll in start-observer.sh (#2356)
* fix(observer): replace hardcoded sleep 2 with PID file poll in start-observer.sh

Fixes #2295

The previous `sleep 2` after launching the observer loop has two
problems: on slow filesystems or loaded systems 2 seconds may not be
enough, producing a false-negative on the subsequent PID file check; on
healthy systems it adds unnecessary latency.

Replace with a poll loop that exits as soon as the PID file appears:

    for _i in $(seq 1 50); do [ -f "$PID_FILE" ] && break; sleep 0.2; done

50 × 0.2s = 10s max wait (vs the previous fixed 2s), but typical startup
returns within the first iteration. No behavior change in the success
path — only the wait strategy changes.

Tests: `node tests/run-all.js` 2891 passed / 0 failed; `npm run lint`,
`catalog:check`, `command-registry:check` all clean.

* test(observer): add regression guard for sleep-2 → PID-file poll (#2295)

Asserts start-observer.sh never reverts to the fixed `sleep 2` wait and
keeps the 50 × 0.2s `$PID_FILE` poll in place. Sits next to the existing
observer-loop invariant block in tests/hooks/hooks.test.js, matching the
repo's pattern of guarding shell-script invariants via source-content
assertions.

Without this, any future "cleanup" that reintroduces a fixed sleep would
silently regress the slow-filesystem fix from the previous commit.

* fix(observer): loosen poll-regression assertions and document failure-path latency (#2356 review)

Addresses CodeRabbit + Greptile feedback on PR #2356:

- tests/hooks/hooks.test.js: split the over-specific positive assertion
  (which pinned the exact `for _i in $(seq 1 50); … sleep 0.2; done`
  line) into three intent-based assertions — bounded iteration count,
  early-exit on $PID_FILE, sub-second interval. Valid refactors (rename
  loop var, switch to `while`, retune to 100 × 0.1s) no longer false-fail
  while the `sleep 2` regression remains guarded.
- start-observer.sh: extend the inline comment to record the trade-off
  Greptile flagged — a loop that crashes before writing $PID_FILE is now
  detected in ~10s instead of ~2s. Healthy startups still return in
  iteration 1.

Tests: node tests/run-all.js (Node v22.18.0) → 2892 passed / 0 failed.
