v0.39.0: workflow completion telemetry + stats aggregation (Phase 3) (#34)

Shahinyanm · web-flow · commit 20843690eafd · 2026-06-03T11:40:56.000+04:00
Completes the fleet arc. Phase 3 in the design note was "WorkflowComplete
event + completion telemetry", originally gated on Claude Code adding a
WorkflowComplete hook. But `workflow end` is already OUR completion
trigger — no CC event needed. Built grounded, no speculation.

Completion telemetry
  - endWorkflow now freezes the live aggregates (used_tokens,
    task_count, over_budget_workers, duration_ms) into a single
    `event:"workflow"` row (code: workflow_complete) in
    hook-events.jsonl. The envelope stores only the static plan;
    freezing the aggregates at end time makes historical analysis
    cheap and survives event-log rotation that could drop the
    per-task rows.

Stats aggregation
  - `token-pilot stats --workflows` — aggregate across all completed
    workflows: count, total tasks, total tokens, over-budget workers,
    plus a per-workflow line with goal + budget %.

Verified end-to-end against the built dist: start → two tagged Task
events (tp-debugger 3000, tp-pr-reviewer 2500) → the BUDGET WATCHDOG
FIRED on both (+329% / +317%) — proof the v0.37.0 totalTokens fix
brought the watchdog back from the dead — → end writes the completion
row → `stats --workflows` shows "1 workflow · 2 tasks · ~5500 tokens
(69% of 8k) · 2 over-budget".

Tests: 1319/1319 pass (+3 completion + stats-workflows).
Build: clean (25 agents under 0.39.0).
