v0.39.2: revert async on PostToolUse:Task (suspected cause of 0 task events) (#36)

Persistent symptom: hook-events.jsonl shows zero `event:"task"` rows
on every machine across many versions, even on v0.39.1 / CC 2.1.161
with 25 agents installed and subagents demonstrably dispatched
(prior `denied` events carry agent_type=code-analyzer/etc).

Investigation (this session):
  - Confirmed the PostToolUse payload schema (`tool_name:"Task"`,
    `tool_response` with authoritative `totalTokens`) — our read path
    is correct.
  - Reproduced hook-post-task locally: fed a realistic payload, it
    writes the task event fine. So the handler is not broken.
  - Confirmed SubagentStop carries no token data (agent_id /
    agent_type / last_assistant_message only) — PostToolUse:Task is
    the right channel.
  - Remaining structural difference between the passing local test and
    production: v0.35.0 added `async: true` to PostToolUse:Task. Under
    async, Claude Code fires the hook DETACHED and does not wait. The
    handler does mkdir + stat + appendFile before exit; a detached
    process can be reaped before those async writes flush. Every event
    that DOES land comes from a synchronous hook (Read deny blocks CC
    until exit, so its write completes) — which fits the evidence.

Fix: drop `async: true` from PostToolUse:Task in both the bundled
hooks.json and the npm installer. post-task now runs synchronously so
the appendEvent write is guaranteed to complete. The ~5ms saved on a
once-per-dispatch hook is not worth losing the telemetry the last
several releases existed to produce.

post-bash KEEPS async: true — it writes no telemetry (advisory
additionalContext only), so detached execution is safe there.

This removes the one confound we control. Next: a fresh-session
subagent dispatch on v0.39.2 is the clean empirical test —
  grep -c '"event":"task"' .token-pilot/hook-events.jsonl
If still 0 after a real dispatch, the cause is elsewhere (likely the
user simply not delegating in that project); if >0, async was it.

Tests: 1319/1319 pass.
