feat(KB-057): add interactive terminal to dashboard

- Add backend terminal API with SSE streaming for real-time output
- Create useTerminal hook with command history and navigation
- Refactor TerminalModal into interactive shell component
- Update App and Header for standalone terminal button
- Add CSS styles for terminal UI (prompts, output, spinner, welcome screen)
- Update tests for new terminal behavior

+The dashboard now includes a fully functional shell terminal accessible via the terminal icon in the header. Features include:
 
-- Real-time command execution with output streaming via SSE
+- Real-time command output streaming via Server-Sent Events (SSE)
 - Command history with Up/Down arrow navigation
-- Support for common commands: git, npm/pnpm/yarn, ls, cat, cd, clear, etc.
+- Keyboard shortcuts: Ctrl+C to kill process, Ctrl+L to clear screen
-- Command validation to block dangerous operations (rm -rf /, etc.)
+- Security validation with allowlist/blocklist for commands
-- Process kill support (Ctrl+C)
+- 30-second timeout for commands with automatic cleanup
-- Clear screen (Ctrl+L)
+- Monospace font styling with color-coded output (stdout/stderr/exit codes)
-- Terminal accessible regardless of task state
+- Mobile-responsive design with safe area insets
+
+The terminal is always available regardless of task state, making it convenient for quick git operations, package management, or debugging without leaving the dashboard.

+### Interactive Terminal
+Access a fully functional shell terminal directly from the dashboard. Click the terminal icon in the header to open the interactive terminal modal.
+
+**Features**:
+- Execute shell commands in the project's working directory
+- Real-time output streaming via Server-Sent Events (SSE)
+- Command history with Up/Down arrow navigation
+- Keyboard shortcuts:
+  - `↑` / `↓` - Navigate command history
+  - `Ctrl+C` - Kill running process
+  - `Ctrl+L` - Clear terminal screen
+  - `Escape` - Close terminal modal
+
+**Supported Commands**:
+The terminal includes a curated allowlist of safe commands including: git, npm/pnpm/yarn, node, python, ls, cat, curl, make, ps, and many more. Dangerous commands (rm -rf /, disk writes, fork bombs, etc.) are automatically blocked for security.
+
+**Session Management**:
+- Each command creates a new session with 30-second timeout
+- Output streams in real-time as the command executes
+- Sessions automatically clean up after exit
+- Terminal state persists while modal is open (clears on close)
