v0.1.0

First release.

lull is the part every chat agent rewrites badly. It waits for a conversation to fall quiet, then hands you one turn instead of four.

What it handles:

• Fragmented messages. Balloons are coalesced into a single turn after quietMs of silence, capped by maxWaitMs. Across 1,000 simulated conversations that is 71.3% fewer model calls (npm run bench, reproducible).
• Redelivered webhooks. The same messageId twice produces one event, tracked in a bounded window.
• Human takeover. The bot goes quiet for a TTL, and messages arriving meanwhile are dropped rather than queued.
• Session expiry. The next turn after inactivity carries isNewSession: true.

The core is a pure reducer that never reads the clock, creates a timer, or touches the network. It returns effects as data, and the facade executes them. That makes concurrency behaviour testable as arithmetic: 30 tests at this tag, three of them property-based, none of them sleeping.

See the CHANGELOG for the full list and the known limitations.
