v0.2.0 — timer-driven, multi-trigger loops

Major refactor modelled on Claude Code's /loop.

Highlights

• Fixed-interval loops (/loop 15m <prompt>): the interval is parsed at the command layer into a cron schedule and run by a self-re-arming timer. Continuation is the default — a loop no longer dies because the model forgot to reschedule, and 15m is a real cadence instead of prompt text.
• Self-paced mode kept as the no-interval form (/loop <prompt>).
• Event & hybrid triggers — fire on pi events (tool_execution_end, turn_end, monitor:done, …) or cron+event with debounce.
• Multiple concurrent loops with LoopCreate / LoopList / LoopDelete tools and /loop list · /loop stop [id].
• Persistence under .pi/loops, restored unexpired on --resume.
• Per-loop maxFires, 7-day expiry, deterministic jitter, read-only mode.

Internals

Split into src/{types,loop-parse,store,scheduler,triggers}.ts; entry stays loop.ts. Added tsconfig, typecheck/test scripts, and node:test coverage for parsing/cron/jitter.
