feat: add hooks functionality with automated workflows

- Introduced hooks to enable automated workflows triggered by specific events during GitHub Copilot sessions.
- Added documentation for hooks in AGENTS.md and README.md.
- Created a new directory structure for hooks, including README.md and hooks.json files.
- Implemented two example hooks: Session Auto-Commit and Session Logger.
- Developed scripts for logging session events and auto-committing changes.
- Enhanced validation and parsing for hook metadata.
- Updated build and validation scripts to accommodate new hooks functionality.

+# 🪝 Hooks
+
+Hooks enable automated workflows triggered by specific events during GitHub Copilot coding agent sessions, such as session start, session end, user prompts, and tool usage.
+### How to Use Hooks
+
+**What's Included:**
+- Each hook is a folder containing a `README.md` file and a `hooks.json` configuration
+- Hooks may include helper scripts, utilities, or other bundled assets
+- Hooks follow the [GitHub Copilot hooks specification](https://docs.github.com/en/copilot/how-tos/use-copilot-agents/coding-agent/use-hooks)
+
+**To Install:**
+- Copy the hook folder to your repository's `.github/hooks/` directory
+- Ensure any bundled scripts are executable (`chmod +x script.sh`)
+- Commit the hook to your repository's default branch
+
+**To Activate/Use:**
+- Hooks automatically execute during Copilot coding agent sessions
+- Configure hook events in the `hooks.json` file
+- Available events: `sessionStart`, `sessionEnd`, `userPromptSubmitted`, `preToolUse`, `postToolUse`, `errorOccurred`
+
+**When to Use:**
+- Automate session logging and audit trails
+- Auto-commit changes at session end
+- Track usage analytics
+- Integrate with external tools and services
+- Custom session workflows
+
+| Name | Description | Events | Bundled Assets |
+| ---- | ----------- | ------ | -------------- |
+| [Session Auto-Commit](../hooks/session-auto-commit/README.md) | Automatically commits and pushes changes when a Copilot coding agent session ends | sessionEnd | `auto-commit.sh`<br />`hooks.json` |
+| [Session Logger](../hooks/session-logger/README.md) | Logs all Copilot coding agent session activity for audit and analysis | sessionStart, sessionEnd, userPromptSubmitted | `hooks.json`<br />`log-prompt.sh`<br />`log-session-end.sh`<br />`log-session-start.sh` |

+# Session Auto-Commit Hook
+
+Automatically commits and pushes changes when a GitHub Copilot coding agent session ends, ensuring your work is always saved and backed up.
+
+## Overview
+
+This hook runs at the end of each Copilot coding agent session and automatically:
+- Detects if there are uncommitted changes
+- Stages all changes
+- Creates a timestamped commit
+- Pushes to the remote repository
+
+## Features
+
+- **Automatic Backup**: Never lose work from a Copilot session
+- **Timestamped Commits**: Each auto-commit includes the session end time
+- **Safe Execution**: Only commits when there are actual changes
+- **Error Handling**: Gracefully handles push failures
+
+## Installation
+
+1. Copy this hook folder to your repository's `.github/hooks/` directory:
+   ```bash
+   cp -r hooks/session-auto-commit .github/hooks/
+   ```
+
+2. Ensure the script is executable:
+   ```bash
+   chmod +x .github/hooks/session-auto-commit/auto-commit.sh
+   ```
+
+3. Commit the hook configuration to your repository's default branch
+
+## Configuration
+
+The hook is configured in `hooks.json` to run on the `sessionEnd` event:
+
+```json
+{
+  "version": 1,
+  "hooks": {
+    "sessionEnd": [
+      {
+        "type": "command",
+        "bash": ".github/hooks/session-auto-commit/auto-commit.sh",
+        "timeoutSec": 30
+      }
+    ]
+  }
+}
+```
+
+## How It Works
+
+1. When a Copilot coding agent session ends, the hook executes
+2. Checks if inside a Git repository
+3. Detects uncommitted changes using `git status`
+4. Stages all changes with `git add -A`
+5. Creates a commit with format: `auto-commit: YYYY-MM-DD HH:MM:SS`
+6. Attempts to push to remote
+7. Reports success or failure
+
+## Customization
+
+You can customize the hook by modifying `auto-commit.sh`:
+
+- **Commit Message Format**: Change the timestamp format or message prefix
+- **Selective Staging**: Use specific git add patterns instead of `-A`
+- **Branch Selection**: Push to specific branches only
+- **Notifications**: Add desktop notifications or Slack messages
+
+## Disabling
+
+To temporarily disable auto-commits:
+
+1. Remove or comment out the `sessionEnd` hook in `hooks.json`
+2. Or set an environment variable: `export SKIP_AUTO_COMMIT=true`
+
+## Notes
+
+- The hook uses `--no-verify` to avoid triggering pre-commit hooks
+- Failed pushes won't block session termination
+- Requires appropriate git credentials configured
+- Works with both Copilot coding agent and GitHub Copilot CLI

+# Session Logger Hook
+
+Comprehensive logging for GitHub Copilot coding agent sessions, tracking session starts, ends, and user prompts for audit trails and usage analytics.
+
+## Overview
+
+This hook provides detailed logging of Copilot coding agent activity:
+- Session start/end times
+- User prompts and questions
+- Session duration
+- Working directory context
+
+## Features
+
+- **Complete Audit Trail**: Track all Copilot interactions
+- **Structured Logging**: JSON format for easy parsing
+- **Searchable History**: Review past sessions and prompts
+- **Analytics Ready**: Export data for usage analysis
+- **Privacy Aware**: Configurable to exclude sensitive data
+
+## Installation
+
+1. Copy this hook folder to your repository's `.github/hooks/` directory:
+   ```bash
+   cp -r hooks/session-logger .github/hooks/
+   ```
+
+2. Create the logs directory:
+   ```bash
+   mkdir -p logs/copilot
+   ```
+
+3. Ensure scripts are executable:
+   ```bash
+   chmod +x .github/hooks/session-logger/*.sh
+   ```
+
+4. Commit the hook configuration to your repository's default branch
+
+## Log Format
+
+Logs are written to `logs/copilot/session.log` in JSON format:
+
+```json
+{
+  "timestamp": "2024-01-15T10:30:00Z",
+  "event": "sessionStart",
+  "sessionId": "abc123",
+  "cwd": "/workspace/project"
+}
+```
+
+## Privacy & Security
+
+- Add `logs/` to `.gitignore` to avoid committing session data
+- Use `LOG_LEVEL=ERROR` to only log errors
+- Set `SKIP_LOGGING=true` environment variable to disable
+- Logs are stored locally only
