Show resolved file paths in agent file-link tooltips (#1088)

* fix: show resolved file paths in agent file-link tooltips

Bare filenames in agent messages now resolve to their full workspace
path on hover. Also raises the daemon's directory-suggestion scan
depth so files in deeper package layouts are reachable.

* fix(app): keep file-link wrapper stable to avoid layout shift on resolve

* fix(app): resolve file links on hover instead of at render time

useQuery was firing the daemon RPC for every ambiguous file reference
the moment a message rendered, fanning out a wave of requests on chat
scroll. Switch to enabled: false + prefetchQuery on hover so RPCs are
driven by user intent. Sync-resolvable refs (directFile, external)
still seed via initialData and render with no RPC.

Also memo on source primitives rather than identity so identical-
content sources constructed inline upstream don't bust the memo every
render.

* Redesign assistant file link resolution

* Stabilize assistant file link handlers
