* 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. Assisted-by: Claude * db : persist per-call tool cwd on tool result messages * ui : abbreviate tool paths under home with a tilde * ui : show the per-call cwd on exec shell rows * ui : clarify the synthetic cwd message for the model * ui : reuse the trailing cwd row on a repeated pick * ui : don't jump when a cwd row is injected mid-chat * chore: Formatting * refactor: Cleanup comments * ui : unify working directory naming and add a synthetic-message flag * ui : render synthetic cwd rows without a scroll jump * ui : decouple the working directory picker into utils and sub-components * ui : add get_info tool call block * chore: Formatting * refactor: Cleanup * refactor: Cleanup * refactor: Cleanup * fix: UI * server : harden file_glob_search listing (kind enum, timeout, symlink guard, absolute base) * ui : use persisted isSynthetic flag for cwd rows, drop legacy formats * ui : cache picker search, fail visibly on native resolve * ui : escape glob metacharacters in picker search glob * ui : simplify auto-scroll pin * chore: Format * fix: Use `SvelteMap` * 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 --------- Co-authored-by: Pascal <admin@serveurperso.com>
