feat: Add JSONC support for oh-my-opencode config files (#275)
Uses Microsoft's jsonc-parser package for reliable JSONC parsing:
- oh-my-opencode.jsonc (preferred) or oh-my-opencode.json
- Supports line comments (//), block comments (/* */), and trailing commas
- Better error reporting with line/column positions
Core changes:
- Added jsonc-parser dependency (Microsoft's VS Code parser)
- Shared JSONC utilities (parseJsonc, parseJsoncSafe, readJsoncFile, detectConfigFile)
- Main plugin config loader uses detectConfigFile for .jsonc priority
- CLI config manager supports JSONC parsing
Comprehensive test suite with 18 tests for JSONC parsing.
Fixes #265
