cce v2.6.5

Fixed

• The workspace dashboard now shows cce mcp --workspace (agent) searches (#28). In workspace mode
  the MCP server writes search events to the workspace-root .cce/metrics.jsonl, but
  cce dashboard --workspace aggregated only the member logs — so agent/MCP searches never appeared in
  totals, recent_searches, or by_source, contradicting docs/mcp.md. The workspace dashboard now
  folds the root log into its roll-up (guarded against double-counting a member that points at the root).
  These federated searches span members and stay out of by_package by design — that panel remains
  per-member. Docs aligned; per-package attribution of agent searches is left as a follow-up option.

Changed

• Faster, correcter workspace federation (#26). Member stores load without building per-member
  BM25 (federation scores only the union's BM25), removing redundant work — full-workspace search is
  ~1.3–2× faster (a real 38.6k-chunk workspace: 3.2s→2.4s CLI). --package short-circuits to load
  only the scoped member(s) (2.08s→1.58s) and now resolves by member name or the package: field,
  erroring with the available list on no match (previously matched member name only and returned
  empty silently). The MCP server caches the assembled union per scope, so repeated
  context_search no longer re-federates (warm call ≈ CLI). Perf/correctness only — ranked results
  are byte-identical (regression-tested); keeps exact brute-force cosine (ANN deferred).
