mahawi1992 700dca22b0 feat(mcp): Add context engineering optimizations (#481) ...

Reduce context window usage by ~80-90% through:

1. Lazy Tool Schema Loading
   - discover_tools(): List tool names only (~500 bytes vs ~15KB)
   - get_tool_info(name): Get specific tool details on-demand

2. Minimal Issue Models
   - IssueMinimal: Lightweight model for list views (~80 bytes vs ~400 bytes)
   - Full Issue model preserved for show() command

3. Result Compaction
   - Auto-compact results with >20 issues
   - Returns preview (5 items) + total count + hint
   - Prevents unbounded context growth

4. Documentation
   - Updated CONTEXT_ENGINEERING.md with patterns and examples

Context savings:
- Tool schemas: 97% reduction (15KB → 500 bytes)
- List 50 issues: 80% reduction (20KB → 4KB)
- Ready work: 80% reduction (4KB → 800 bytes)

Inspired by MCP Bridge (github.com/mahawi1992/mwilliams_mcpbridge)
and Manus context engineering patterns.
