Add a new terminal UI crate (crates/app/ui) built with ratatui providing an
interactive chat interface with real-time LLM streaming and tool visualization.
Features:
- Chat panel with horizontal padding for improved readability
- Input box with cursor navigation and command history
- Status bar with session statistics and uniform background styling
- 7 theme presets: Tokyo Night (default), Dracula, Catppuccin, Nord,
Synthwave, Rose Pine, and Midnight Ocean
- Theme switching via /theme <name> and /themes commands
- Streaming LLM responses that accumulate into single messages
- Real-time tool call visualization with success/error states
- Session tracking (messages, tokens, tool calls, duration)
- REPL commands: /help, /status, /cost, /checkpoint, /rewind, /clear, /exit
Integration:
- CLI automatically launches TUI mode when running interactively (no prompt)
- Falls back to legacy text REPL with --no-tui flag
- Uses existing agent loop with streaming support
- Supports all existing tools (read, write, edit, glob, grep, bash)

Add complete agent orchestration system that enables LLM to call tools:
**Core Agent System** (`crates/core/agent`):
- Agent execution loop with tool call/result cycle
- Tool definitions in Ollama-compatible format (6 tools)
- Tool execution with permission checking
- Multi-iteration support with max iteration safety
**Tool Definitions**:
- read: Read file contents
- glob: Find files by pattern
- grep: Search for patterns in files
- write: Write content to files
- edit: Edit files with find/replace
- bash: Execute bash commands
**Ollama Integration Updates**:
- Extended ChatMessage to support tool_calls
- Added Tool, ToolCall, ToolFunction types
- Updated chat_stream to accept tools parameter
- Made tool call fields optional for Ollama compatibility
**CLI Integration**:
- Wired agent loop into all output formats (Text, JSON, StreamJSON)
- Tool calls displayed with 🔧 icon, results with ✅
- Replaced simple chat with agent orchestrator
**Permission Integration**:
- All tool executions check permissions before running
- Respects plan/acceptEdits/code modes
- Returns clear error messages for denied operations
**Example**:
User: "Find all Cargo.toml files in the workspace"
LLM: Calls glob("**/Cargo.toml")
Agent: Executes and returns 14 files
LLM: Formats human-readable response
This transforms owlen from a passive chatbot into an active agent that
can autonomously use tools to accomplish user goals.
Tested with: qwen3:8b successfully calling glob tool

Milestone M6 implementation adds a comprehensive hook system that allows
users to run custom scripts at various lifecycle events.
New crate: crates/platform/hooks
- HookEvent enum with multiple event types:
* PreToolUse: fires before tool execution, can deny operations (exit code 2)
* PostToolUse: fires after tool execution
* SessionStart: fires at session start, can persist env vars
* SessionEnd, UserPromptSubmit, PreCompact (defined for future use)
- HookManager for executing hooks with timeout support
- JSON I/O: hooks receive event data via stdin, can output to stdout
- Hooks located in .owlen/hooks/{EventName}
CLI integration:
- All tool commands (Read, Write, Edit, Glob, Grep, Bash, SlashCommand)
now fire PreToolUse hooks before execution
- Hooks can deny operations by exiting with code 2
- Hooks timeout after 5 seconds by default
Tests added:
- pretooluse_can_deny_call: verifies hooks can block tool execution
- posttooluse_runs_parallel: verifies PostToolUse hooks execute
- sessionstart_persists_env: verifies SessionStart can create env files
- hook_timeout_works: verifies timeout mechanism
- hook_not_found_is_ok: verifies missing hooks don't cause errors
All 63 tests passing.

This commit implements the complete M1 milestone (Config & Permissions) including:
- New permissions crate with Tool, Action, Mode, and PermissionManager
- Three permission modes: Plan (read-only default), AcceptEdits, Code
- Pattern matching for permission rules (exact match and prefix with *)
- Integration with config-agent for mode-based permission management
- CLI integration with --mode flag to override configured mode
- Permission checks for Read, Glob, and Grep operations
- Comprehensive test suite (10 tests in permissions, 4 in config, 4 in CLI)
Also fixes:
- Fixed failing test in tools-fs (glob pattern issue)
- Improved glob_list() root extraction to handle patterns like "/*.txt"
All 21 workspace tests passing.
