feat(#59): implement wiki-link parser

- Created wiki-link-parser.ts utility for parsing [[links]] syntax
- Supports multiple formats: [[Page Name]], [[Page|display]], [[slug]]
- Returns parsed links with target, display text, and position info
- Handles edge cases: nested brackets, escaped brackets, code blocks
- Code block awareness: skips links in inline code, fenced blocks, and indented code
- Comprehensive test suite with 43 passing tests (100% coverage)
- Updated README.md with parser documentation

Implements KNOW-007 (Issue #59) - Wiki-style linking foundation
