DashMap::clone() deep-copies all entries into a new map. The MCP
server's cloned SshService/SftpService/RdpService/ScrollbackRegistry
were snapshots from startup that never saw new sessions.
Fix: wrap all DashMap fields in Arc<DashMap<...>> so clones share
the same underlying map. Sessions added after MCP startup are now
visible to MCP tools.
Affected: SshService, SftpService, RdpService, ScrollbackRegistry.

On startup, Wraith checks if wraith-mcp-bridge exists in the data
directory. If missing or version mismatch, downloads the correct
version from Gitea packages automatically. No installer changes needed.
Flow:
1. Check data_dir/wraith-mcp-bridge.exe exists
2. Check data_dir/mcp-bridge-version matches app version
3. If not, download from packages/vstockwell/generic/wraith/{ver}/
4. Set execute permissions on Unix
5. Write version marker
Also exposes mcp_bridge_path command so the frontend can show the
path in settings for users to add to PATH or configure Claude Code.

Resizable panel:
- Drag handle on left border of copilot panel
- Pointer events for smooth resize (320px–1200px range)
SFTP MCP tools:
- sftp_list: list remote directories
- sftp_read: read remote files
- sftp_write: write remote files
- Full HTTP endpoints + bridge tool definitions
Active session context:
- mcp_get_session_context command returns last 20 lines of scrollback
- Frontend can call on tab switch to keep AI informed
Error watcher:
- Background scanner runs every 2 seconds across all sessions
- 20+ error patterns (permission denied, OOM, segfault, disk full, etc.)
- Emits mcp:error events to frontend with session ID and matched line
- Sessions auto-registered with watcher on connect

Complete MCP communication pipeline:
Backend HTTP server (axum on localhost:0):
- POST /mcp/sessions — list active sessions
- POST /mcp/terminal/read — read scrollback (ANSI stripped)
- POST /mcp/terminal/execute — send command + marker, capture output
- Port written to data_dir/mcp-port at startup
- Shares SshService and ScrollbackRegistry with AppState via Clone
Bridge binary (wraith-mcp-bridge):
- Speaks JSON-RPC 2.0 over stdio (MCP protocol)
- Translates tool calls to HTTP requests against running Wraith
- Implements initialize, tools/list, tools/call
- Exposes: terminal_read, terminal_execute, list_sessions
- Reads MCP port from data_dir/mcp-port
Auto-config:
- PTY spawn injects WRAITH_MCP_BRIDGE env var
- SshService and ScrollbackRegistry derive Clone for sharing

Infrastructure for the Wraith Terminal MCP server:
- ScrollbackBuffer: 64KB circular buffer per session with ANSI stripping
- ScrollbackRegistry: DashMap registry shared between output loops and MCP
- SSH output loop feeds scrollback in addition to emitting events
- PTY output loop feeds scrollback in addition to emitting events
- mcp_terminal_read: read last N lines from any session (ANSI stripped)
- mcp_terminal_execute: send command + marker, capture output until marker
- mcp_list_sessions: enumerate all active SSH sessions with metadata
8 new scrollback tests (ring buffer, ANSI strip, line limiting).
95 total tests, zero warnings.
Bridge binary and auto-config injection to follow.
