feat: implement Obsidian MCP Bundle MVP (Phase 1-3)
- Complete project setup with TypeScript, Jest, MCPB manifest - Implement foundational infrastructure (CLI executor, logger, error handler) - Add 9 file operation tools for User Story 1 - Full MCP protocol compliance with stdio transport - Input validation and sanitization for security - Comprehensive error handling with actionable messages - Constitutional compliance: all 6 principles satisfied MVP includes: - obsidian_create_note, read, append, prepend, delete, move, rename, open, file_info - Zod validation schemas for all parameters - 30s timeout configuration with per-command overrides - Stderr-only logging with sanitized output - Graceful shutdown handling Build: ✅ 0 errors, 0 vulnerabilities Tasks: 48/167 complete (MVP milestone) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
