joaovictorolvr fe8737420d fix(hooks): soft-fail SessionStart health check on cold start
The three SessionStart hooks poll http://localhost:37777/health with an
8-second retry budget and then exit 1 silently (via `curl -sf || exit 1`)
when the worker has not stabilized in time. Claude Code surfaces this as
two `SessionStart:startup hook error - Failed with non-blocking status
code: No stderr output` messages on every first session of the day.

This happens because of a race between the MCP server auto-starting the
worker and the hook's own `worker-service.cjs start` path, which on Linux
respects a live PID file written by an earlier session and waits for the
existing worker to become healthy. 8s is not always enough.

Mitigate in the hook layer without touching worker-service.cjs:

- bump the inner retry loop from 8 to 20 attempts (up to ~20s)
- replace `|| exit 1` with `|| true` so the hook emits its continue JSON
  regardless (Claude Code no longer logs a phantom error)
- guard the context-injection hook with a health check - only run
  `worker-service.cjs hook claude-code context` if the worker is actually
  responding, otherwise skip silently

Trade-off: on cold starts where the worker takes longer than ~20s to
come up, the recent-context preamble is skipped for that first session
instead of surfacing an error. Subsequent sessions in the same day work
normally because the worker is already healthy.
