* base : @-mention picker foundation - glob search, picker nav, highlight
* feat : @-mention file/folder picker and mention badges in message bubbles
* fix: Imports
* feat : wire the @-mention picker into the chat form
* fix: Bound the glob-search result cache key and prune stale entries
* server : extend file_glob_search for UI pickers
* ui : add per-conversation working directory with picker
* ui : add path navigation and search scope to cwd picker
Treat path-like queries (starting with / or ~) as directory navigation
instead of glob-matching the whole query: search the parent for the last
segment, and descend into an exactly-typed directory by listing its
children. Show the effective search scope in the footer and auto-search
on open so the current directory and its siblings appear immediately.

* refactor: Post-review fixes
* ui: accept Windows roots in the working directory picker
recognize a drive root (C:) and a UNC share (//host/share) as path
navigation, alongside the POSIX root and ~, so a query like D:\repos
lists that directory instead of glob-matching it under the home dir
split below the root, so a bare drive resolves to its root rather than
to a drive-relative prefix
rewrite backslashes into forward slashes only when the query carries a
Windows root, since a backslash is a legal POSIX filename character
paths keep travelling with forward slashes, which is what the server
returns and what Windows accepts
