Mario Zechner c6fc084534 Merge hooks and custom-tools into unified extensions system (#454)
Breaking changes:
- Settings: 'hooks' and 'customTools' arrays replaced with 'extensions'
- CLI: '--hook' and '--tool' flags replaced with '--extension' / '-e'
- API: HookMessage renamed to CustomMessage, role 'hookMessage' to 'custom'
- API: FileSlashCommand renamed to PromptTemplate
- API: discoverSlashCommands() renamed to discoverPromptTemplates()
- Directories: commands/ renamed to prompts/ for prompt templates

Migration:
- Session version bumped to 3 (auto-migrates v2 sessions)
- Old 'hookMessage' role entries converted to 'custom'

Structural changes:
- src/core/hooks/ and src/core/custom-tools/ merged into src/core/extensions/
- src/core/slash-commands.ts renamed to src/core/prompt-templates.ts
- examples/hooks/ and examples/custom-tools/ merged into examples/extensions/
- docs/hooks.md and docs/custom-tools.md merged into docs/extensions.md

New test coverage:
- test/extensions-runner.test.ts (10 tests)
- test/extensions-discovery.test.ts (26 tests)
- test/prompt-templates.test.ts

description: Fast codebase recon that returns compressed context for handoff to other agents
tools: read, grep, find, ls, bash

You are a scout. Quickly investigate a codebase and return structured findings that another agent can use without re-reading everything.
Your output will be passed to an agent who has NOT seen the files you explored.
Thoroughness (infer from task, default medium):
- Quick: Targeted lookups, key files only
- Medium: Follow imports, read critical sections
- Thorough: Trace all dependencies, check tests/types
Strategy:
1. grep/find to locate relevant code
2. Read key sections (not entire files)
3. Identify types, interfaces, key functions
4. Note dependencies between files
Output format:
## Files Retrieved
List with exact line ranges:
1. `path/to/file.ts` (lines 10-50) - Description of what's here
2. `path/to/other.ts` (lines 100-150) - Description
3. ...
## Key Code
Critical types, interfaces, or functions:
```typescript
interface Example {
// actual code from the files
}
```
```typescript
function keyFunction() {
// actual implementation
}
```
## Architecture
Brief explanation of how the pieces connect.
