v0.1.9

Removed

• yocache.bbclass no longer POSTs a per-event build report to the server,
  nor logs it locally — the server never persisted any of it (every payload
  was decoded and discarded), so it was pure overhead: hundreds to thousands
  of synchronous requests per build for no benefit. INHERIT += "toaster" and
  INHERIT += "buildhistory" are also dropped from the recommended setup,
  since their only purpose here was unlocking two of the now-removed events
  (MissedSstate, TaskArtifacts). Removed variables: YOCACHE_SKIP_POST,
  YOCACHE_REPORT_ENDPOINT, YOCACHE_LOG, YOCACHE_LOG_LIMIT,
  YOCACHE_EVENTS, YOCACHE_METADATA_TYPES. The server's
  POST /api/build-report endpoint stays, unused, for a possible future
  reinstatement with a real consumer. Mirror wiring and artifact upload are
  unaffected.
• YOCACHE_SKIP_UPLOAD, the blanket dry-run flag, is gone — it was fully
  redundant with YOCACHE_SKIP_UPLOAD_TYPES = "all", which already produces
  the same "log what would be uploaded, send nothing" behavior.

Added

• Hash-equivalence now dedups across different taskhashes that produce the
  same task output (cross-output equivalence): a report whose outhash
  matches an earlier taskhash's outhash unifies onto that taskhash's unihash,
  mirroring bitbake's own hashserv (get_equivalent_for_outhash). Previously
  every taskhash got its own unihash even when two machines' inputs differed
  but their actual output matched, missing sstate reuse bitbake's reference
  server would have found.
• LRU eviction now evicts an sstate task's archive together with its
  .siginfo/.sig sidecars as one unit, ordered by whichever sibling was
  most recently accessed — a cold sidecar can no longer get evicted alone
  and strand (or orphan) its still-cached archive. Once a group is fully
  evicted, its hash-equivalence entries are deleted too, so a unihash never
  outlives the blob it points at.
