SFTP tab switch fix:
- Removed :key on FileTree that destroyed component on every switch
- useSftp now accepts a reactive Ref<string> sessionId
- Watches sessionId changes and reinitializes without destroying state
- Per-session path memory via sessionPaths map — switching back to a
tab restores exactly where you were browsing
CWD following fix (macOS + all platforms):
- Injects OSC 7 prompt hook into the shell after SSH connect
- zsh: precmd() emits \e]7;file://host/path\e\\
- bash: PROMPT_COMMAND emits the same sequence
- Sent via the PTY channel so it configures the interactive shell
- The passive OSC 7 parser in the output loop picks it up
- SFTP sidebar auto-navigates to the current working directory

Remote monitoring bar:
- Slim 24px bar at bottom of every SSH terminal
- CPU, RAM, disk, network stats polled every 5s via exec channel
- Cross-platform: Linux (/proc), macOS (vm_stat/sysctl), FreeBSD
- Color-coded thresholds: green/amber/red
- No agent installation — standard POSIX commands only
SFTP follows active tab:
- Added :key="activeSessionId" to FileTree component
- Vue recreates FileTree when session changes, reinitializing SFTP
CWD tracking fix (macOS + all platforms):
- Old approach: exec channel pwd — returns HOME, not actual CWD
- New approach: passive OSC 7 parsing in the output stream
- Scans for \e]7;file://host/path\a without modifying data
- Works with bash, zsh, fish on both Linux and macOS
- Zero corruption risk — data passes through unmodified
- Includes URL percent-decoding for paths with spaces

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.

Replaced the openssl CLI fallback with pure Rust crypto for EC private
keys in SEC1 format (-----BEGIN EC PRIVATE KEY-----). Handles PKCS#5
encrypted keys (AES-128-CBC + MD5 EVP_BytesToKey KDF) and converts to
PKCS#8 PEM that russh can parse natively.
All crypto crates (md5, aes, cbc, sec1, pkcs8) were already in the dep
tree via russh — just promoted to direct dependencies. Zero new binary
dependencies, works on Windows without openssl installed.

russh only parses 4 PEM headers: OPENSSH, RSA, PKCS8, ENCRYPTED PKCS8.
EC keys (-----BEGIN EC PRIVATE KEY-----) with PKCS5 encryption silently
failed with "Could not read key".
Fix adds two fallbacks:
1. If russh can't parse the key, convert to PKCS8 via `openssl pkey`
which handles EC, DSA, and all other OpenSSL-supported formats
2. If the input doesn't start with -----BEGIN, try reading it as a
file path (supports ~ expansion) for keys stored on disk

Root cause: The output reader loop held Arc<TokioMutex<Channel>> while
calling ch.wait().await. After the initial prompt rendered and the server
went idle, wait() blocked indefinitely holding the lock. ssh_write()
could never acquire the mutex to send keystrokes. Permanent deadlock.
Fix: Separated read/write paths. The output loop now owns the Channel
exclusively via tokio::select!, receiving resize/shutdown commands through
an mpsc channel. Writes go through Handle::data(channel_id, data) which
bypasses the Channel entirely — no shared mutex, no deadlock.
Also killed all compiler warnings (unused imports in rdp module).

Rust SSH service: russh async client, DashMap session registry,
TOFU host key verification, CWD tracking via separate exec channel
(never touches terminal stream), base64 event emission for terminal
I/O. 52/52 tests passing.
Vue 3 frontend: ported from Wails v3 to Tauri v2 — useTerminal
composable with streaming TextDecoder + rAF batching, session store
with multi-connection support, connection store/tree, sidebar, tab
bar, status bar, keyboard shortcuts. All Wails imports replaced
with Tauri API equivalents.
