Part of #627.

Adds fragment search <name> '<words>' --dir <folder> [--limit N], with the CLI's normal --json envelope. It reads current working Markdown offline, with no login, brain server, sync pass or watcher. Unsynced edits and local-only files are immediately searchable; deleted files disappear between invocations.

The disposable index is SQLite FTS5 in memory, rebuilt on every call. All query words are required prefixes; weighted BM25 ranks title (4), heading (3), path/ancestry (2) and body (1). Results identify fragment, path, title, heading, ancestry, excerpt and synced, local_only or conflicted state. Sync records divergence in an optional journal field so an unsuccessful remote-copy write cannot make adopted local bytes appear agreed. Existing conflict copies and merge markers also warn; remote copies are not separate truth-bearing hits.

Validation:

• cargo test -p fragment-cli --offline: CLI unit tests and real-binary integration tests, including offline same-size edits, local additions, deletion/restart, journal and sibling-copy conflicts, merge markers, ranking/prefixes, limits, skipped files, invalid input and symlink exclusion.
• cargo xtask check: JavaScript syntax/guards, schema lock, workspace tests, host and Wasm Clippy with warnings denied.
• git diff --check.

Caveats: synced means matching the last local journal, not a fresh remote/published-content check. Each call reads all eligible pages; concurrent edits are not an atomic filesystem snapshot. Sync's ignore rules apply. Pages >=1 MiB, non-UTF-8 content and sections beyond the first 500 are reported as skipped. The CommonMark parser includes Setext headings, scalar frontmatter and inline tags; multiline YAML tags are not interpreted, and long sections split at 8000 Unicode characters. Older journals cannot identify a conflict whose remote copy was never saved. Full command/output and conflict semantics are documented in the CLI guide and brain README.

Scoped to local lexical search: no embeddings, services, path ACLs, collections, cell API changes or deployment.

The rerun of the failed jobs is green. All CI checks now pass: the unrelated chat-layout wait in shard 3 cleared, and brain-search checks plus all four e2e shards pass.

Closing per Paul (2026-10-30): search goes through the platform. A fragment's own index (#783, on the LanceDB service #777) gets the fragment search name, and agents already search well on their own. A local search may come back later as a separate, differently named command. The branch is kept.
