Update runtime state and ignore generated media and analytics

Runtime state written by the app: session checkpoint, used-topics history,
regulars, intern lookups, voicemails, publish state through episode 58, and the
website clips index.

Also ignores what should never enter history: clips/, music/, mlx_models/,
remotion-demo/ and social_posts/ come to roughly 13 GB of media and model
weights, and data/costs.db is a binary SQLite database that cost_tracker
rewrites on every LLM call — committing it would attach a multi-megabyte delta
to future commits. cost_reports/ and avatars/ are regenerable, and reaper/peaks/
is a waveform cache.
