Adam Moussa f05a98dba1 Add JSONL telemetry and weekly summary (Phase 4)
Observability slim layer. Every full run appends one JSON line to
~/.claude/logs/orchestrator/YYYY-MM-DD.jsonl with timestamp, sha256-prefix
task hash (raw task is never logged), retrieved memory names, router
choice, runtime, tokens in/out, success/error. risk_class and confidence
fields are reserved nulls for Phase 5.

- telemetry.py: log_run(), build_record(), task_hash(), token-usage
  extraction from AIMessage.usage_metadata. log_run swallows all
  exceptions — telemetry never kills a run.
- run.py: wraps app.invoke in try/except with a monotonic-clock window;
  logs on both success and failure. --route-only path is left unlogged
  (no agent work, doesn't represent a "run").
- scripts/weekly_summary.py: scans the last 7 days of JSONL and prints
  a markdown digest (routes, unknown rate, cross-review rate, success
  rate, total spend, mean tokens/route). Schedule via /schedule and
  pipe stdout to Slack from the scheduler.

Cost rates per route are rough Sonnet/Haiku/GPT/Gemini/DeepSeek defaults
suitable for spotting runaway prompts, not finance. Router tokens for
structured-output calls aren't captured (they don't surface through the
message trail); agent tokens are the dominant component anyway.

Validated: golden-set 21/21 still passing; full-run smoke writes
expected fields; weekly_summary.py prints clean markdown from a 2-run
log.

"""JSONL telemetry for orchestrator runs.
Appends one JSON line per run to ~/.claude/logs/orchestrator/YYYY-MM-DD.jsonl.
Logging failures are swallowed — telemetry must never kill the orchestrator.
Fields (Phase 4):
timestamp ISO-8601 UTC
task_hash sha256(task)[:16] — never log raw task content
retrieved list[str] — memory names surfaced by the retriever
route str | None — the router's choice (or None on early failure)
risk_class null — placeholder for Phase 5
confidence null — placeholder for Phase 5
runtime_seconds float
tokens_in int
tokens_out int
success bool
error str | None — type+message if the run raised
