The cache-size gauges come from an in-memory index that assumes the proxy owns the cache dir, so a mirror deleted by hand left them stale until restart. The eviction task now reconciles the index against disk on a timer, dropping entries whose path has vanished and refreshing the gauges. Closes #59. Assisted-by: Claude:claude-opus-4-8
Document that the cache is self-managing and that `--cache-max-mb` is the intended way to reclaim disk, since manual mirror deletion is tolerated but not the supported lever (see #59). Assisted-by: Claude:claude-opus-4-8

Expose the configured cache cap (cache_max_bytes) and fetch TTL (fetch_ttl_seconds) as static gauges set at startup, so a dashboard can compute cache utilization without hardcoding the cap (see #57). Assisted-by: Claude:claude-opus-4-8
Add cache_outcome_total{outcome=cloned|fetched|cached}, recorded once
per info/refs advertisement where the clone/fetch/TTL decision is made.
It is the local-vs-upstream signal: the share served without touching
upstream is cached / sum without (outcome) (...). The outcome was
already computed by ensure_fresh and discarded; this wires it up.
Closes #57.

Summary
The cache-size gauges come from an in-memory index that assumes the proxy owns the cache dir, so a mirror deleted by hand left them stale until restart - see #59. The eviction task now reconciles the index against disk on a timer, dropping entries whose path has vanished and refreshing the gauges.
Also, address pt. 2 and 3 from #57.
