Summary

Closes #47 — implements @file mention feature.

Changes

Backend (Go)

UserMessage → multi-part: Content string → Parts []UserPart (UserTextPart + UserFileMentionPart), with backward-compatible JSON
new internal/mention package: parses @path/to/file mentions, reads file content, generates structured UserParts
hook in pool.Execute + EmbeddedService: both daemon and TUI paths parse @mentions before storing user message
GET /api/fs/tree?session_id=&search=: returns filtered file list using fd → find → Go WalkDir fallback chain

Frontend (TS/React)

Tiptap replaces textarea: rich text editor with Mention extension for @file autocomplete chips
80ms debounced search: calls /api/fs/tree backend endpoint for fuzzy file matching
Inline mention chips: styled with background color, file icon, atomic deletion
User message rendering: file mention chips displayed in chat history
TypeScript types: hand-written UserPart discriminated union (same pattern as AssistantPart)

Prompt format

File contents injected as XML blocks after user text:

user text here

<file_content path="src/main.go">
package main
...
</file_content>
