feat(server): add skill generator for SKILL.md creation

Add two new MCP tools for generating Claude Code skills:
- `generate_skill` - builds context and prompt for LLM generation
- `save_skill` - validates and saves generated SKILL.md

Key features:
- Token-efficient template (<500 tokens) focused on bash commands
- Progressive loading pattern: ls, cat, grep, node
- LazyLock pre-compiled regexes for performance
- JSDoc metadata parsing from TypeScript files
- Comprehensive test coverage (550 tests)

New modules:
- skill/parser.rs - TypeScript file parser
- skill/context.rs - Skill context builder
- skill/template.rs - Handlebars template rendering
