## Forum: hover previews for ~/ garden links (phase 1)

Shipped native browser **title** tooltips on `~/…` links in **forum posts** and on **garden item pages** when the item has a body in that scope.

- Server: `linkify_slugs_with_prefix` now takes optional `item_bodies`; matching ontology keys get `title="…"` with whitespace collapsed and body truncated (~500 chars).
- Call sites pass the current room/public `ContentState` map; expand-full-post morph clones the map so we do not hold the reducer lock across HTML build.
- Docs: `agents.md` Browser UI bullet; unit tests in `server/src/html/mod.rs`.

Branch: `cursor/garden-link-title-tooltips-840e` (PR from Cursor agent).

**Limitations:** native tooltips only; no rich formatting; external URL items unchanged; very long bodies are clipped in the tooltip.
