Alluvia 0.2.0 — the good citizen

The good-citizen release: alluvia now runs concurrently, dies cleanly, shows
you everything it keeps, and repairs itself (#5, #6, #7, #8).

• Concurrent sessions (#5) — the store runs in WAL mode (readers never
  block a running refresh; legacy stores upgrade transparently), refresh
  takes a single-writer lock released by the OS on any process death
  ("already running (pid N)" instead of double-spending your LLM budget),
  and serve reuses an already-running dashboard or walks to a free port.
• Kill-anytime contract (#5) — any alluvia process can be killed at any
  instant with zero corruption and zero cleanup debt. SIGTERM behaves like
  Ctrl-C; interrupting a refresh prints "paused — everything done so far is
  saved" and resumes on the next run.
• alluvia status (#6) — every path alluvia touches with sizes, the
  store broken down by data class (raw = source of truth · derived =
  rebuildable · judgments = yours), and what's live right now. --json for
  scripting.
• alluvia doctor (#7) — diagnoses the whole installation and applies
  every safe repair automatically: WAL on legacy stores, schema migrations,
  pruning orphaned derived rows, config permissions, stale digest flags,
  impossible governor cooldowns. Raw data and judgments are never touched.
  --check reports without repairing (exit 1 if repairs are needed),
  --live proves your provider key with one tiny call, and
  --rebuild-derived is the confirmed recovery lever that discards derived
  data while raw sessions and your ratings survive.
• --verbose and refresh --plan (#8) — see the pipeline and governor
  think; preview exactly what a refresh would do (sessions pending, theme
  work, cooldowns in effect) without spending a single LLM call.
