feat: improve CLI help and rename session to logs command (#36)
- Rename 'session' command to 'logs' for clarity - Change logs command to only print paths instead of opening files - Add comprehensive custom help command with detailed information - Align help output with README content including: - Overview and purpose - Quick start guide - File structure visualization - Requirements and installation - Hook types descriptions - Command examples - Links to documentation 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: Claude <[email protected]>

### Known Issues and Solutions
72+
73+
#### TypeScript Warning in Production
74+
**Problem**: When users run `npx claude-hooks`, they may see:
75+
```
76+
Warning: Could not find typescript. Please ensure that typescript is a devDependency.
77+
```
78+
79+
**Root Cause**: Oclif checks for TypeScript during module import, not during execution. It searches for tsconfig.json starting from the current working directory and moving up the directory tree.
80+
81+
**Solution**: Set `NODE_ENV=production` in bin/run.js BEFORE importing @oclif/core:
82+
```javascript
83+
// Set production mode before importing to prevent TypeScript detection
84+
process.env.NODE_ENV = 'production'
85+
86+
import {execute} from '@oclif/core'
87+
```
88+
89+
**Why other approaches don't work**:
90+
- Setting `development: false` in execute() is too late - the check happens during import
91+
- Setting `OCLIF_TS_NODE=0` doesn't prevent the initial TypeScript check
92+
- Intercepting stderr is a hack that masks the real issue
93+
94+
## Best Practices & Lessons Learned
95+
96+
### Always Test with the Actual Published Package
97+
Before declaring a fix complete, always test with the actual npm package:
98+
```bash
99+
npx package-name@latest
100+
```
101+
Testing only locally can miss issues that appear in the published version.
102+
103+
### Updating Help Documentation
104+
When improving CLI help:
105+
1. Update package.json description to match README
106+
2. Update command descriptions in the static description field
107+
3. Run `npx oclif manifest` after changes to update the manifest
108+
4. Consider removing irrelevant plugins (like `@oclif/plugin-plugins` if not needed)
109+
110+
### Git Workflow
111+
1. Always verify fixes work before committing
112+
2. Use `--no-verify` flag sparingly when git hooks have issues
113+
3. Check PR status with `gh pr checks <number>`
114+
4. Enable automerge with `gh pr merge <number> --auto --squash`
115+
116+
### Debugging Oclif Issues
117+
1. Oclif searches for configuration starting from the current working directory
118+
2. Module loading happens before execute() is called
119+
3. Use `NODE_ENV=production` to affect behavior during import time
120+
4. The `development` flag in execute() only affects runtime behavior
121+
122+
### Testing Strategy
123+
- Test from different directories to catch path-related issues
124+
- Test with a tsconfig.json in the current directory
125+
- Ensure all existing tests pass before pushing
126+
- Clean up test directories after testing
127+
128+
### Common Pitfalls to Avoid
129+
1. Don't assume environment variables set after import will affect module loading
130+
2. Don't rely on intercepting stdout/stderr as a permanent solution
131+
3. Always test the exact scenario users will experience
132+
4. Remember that published packages don't include devDependencies
