MCP 1.0.31

• Search never tells an agent the index is stale or to grep. The API now
  keeps each project's default branch indexed from its GitHub remote, with no
  machine or checkout involved (contextstream API migration 853), and reports
  index_trust.canonical.state (current, catching_up, unverified).
  • Freshness follows that state, not the age of the last write: an index that
    holds the remote head is fresh however long ago the last push was, and one
    the server is syncing is not stale.
  • Default search output no longer carries index_health, index_trust or
    ingested_at_max; they appear with CONTEXTSTREAM_DEBUG=1 and in
    project(action="index_status"). When the server confirms the index holds
    the remote head, search adds index_source (repository, branch,
    head, current).
  • No index recommendation names a path any more. A project's recorded path
    can belong to a machine that no longer exists; the
    init(folder_path=...) advice remains only for a folder this process has
    just read.
  • project_index_state is never rewritten to stale from an age.
  • A checkout on another branch or commit is not flagged [INDEX_TRUST] when
    the index follows the remote, and [INDEX_CHECKOUT] notes about other
    machines' checkout roots are dropped for such projects.
  • project(action="index_status") says which remote branch the index
    follows and whether it holds its head.
• Searching another project of the same workspace no longer raises
  [SCOPE_MISMATCH]: the server answers it from that project's current
  default branch, with no checkout or init. Across workspaces it still warns.
