* feat(help): add markdown parsing and section extraction
Implements #137: markdown parsing and section extraction for help system.
- Add Topic and Section types for help content structure
- Add Frontmatter type for YAML metadata parsing
- Add ParseTopic() to parse markdown files into Topic structs
- Add ExtractFrontmatter() to extract YAML frontmatter
- Add ExtractSections() to extract headings and content
- Add GenerateID() to create URL-safe anchor IDs
- Add comprehensive tests following _Good/_Bad naming convention
This is the foundation for the display-agnostic help system (#133).

* fix(test): use manual cleanup for TestDevOps_Boot_Good_FreshWithNoExisting
Fixes flaky test that fails with "TempDir RemoveAll cleanup: directory
not empty" by using os.MkdirTemp with t.Cleanup instead of t.TempDir().
This is the same fix applied to TestDevOps_Boot_Good_Success in 8effbda.

* fix(help): address CodeRabbit review feedback
- Add CRLF line ending support to frontmatter regex
- Add empty frontmatter block support
- Use filepath.Base/Ext for cross-platform path handling
- Add tests for CRLF and empty frontmatter cases

* feat(help): add full-text search functionality
Implements #139: full-text search for help topics.
- Add searchIndex with inverted index for fast lookups
- Add tokenize() for case-insensitive word extraction
- Add Search() with relevance ranking:
- Exact word matches score 1.0
- Prefix matches score 0.5
- Title matches get 2.0 boost
- Add snippet extraction for search result context
- Add section-level matching for precise results
- Add comprehensive tests following _Good/_Bad naming
Search features:
- Case-insensitive matching
- Partial word matching (prefix)
- Title boost (matches in title rank higher)
- Section-level results
- Snippet extraction with context

* fix(help): use rune-based slicing for UTF-8 safe snippets
Address CodeRabbit feedback: byte-based slicing can corrupt multi-byte
UTF-8 characters. Now uses rune-based indexing for snippet extraction.
- Convert content to []rune before slicing
- Convert byte position to rune position for match location
- Add UTF-8 validation tests with Japanese text

* fix(help): use correct string for byte-to-rune conversion in extractSnippet
strings.ToLower can change byte lengths for certain Unicode characters
(e.g., K U+212A 3 bytes → k 1 byte). Since matchPos is a byte index from
strings.Index(contentLower, word), the rune conversion must also use
contentLower to maintain correct index alignment.
Fixes CodeRabbit review feedback.
