trace_callers, trace_callees, transitive_impact, and find_all_references could silently answer from a stale graph after a branch switch, rebase, uncommitted edit, or a watcher that missed changes while its process was down — nothing in the response indicated the graph might not match the working tree. Adds a freshness module that stamps the git HEAD a project's graph was last built from (.infigraph/index_meta.json) and compares it against live git state (HEAD, working-tree dirtiness, pending watcher reindex) to prepend a stale-graph warning on the affected tools. Watcher startup now also reconciles against the stored HEAD once before entering its event loop, so a restarted watcher catches commits made while it was down instead of waiting for an unrelated future file write. Verified with unit/integration tests plus a Docker harness (docker/freshness-test/) simulating all three failure modes end-to-end against compiled binaries.
