v1.7.7: improve lint accuracy — reduce false positives, catch dead rules

Lint accuracy (tested against 8 real-world repos):
- Context-aware vague rule detection: skip qualified phrases like
  'be consistent with X' or 'follow best practices for Y'
- Detect non-functional rules: alwaysApply:false + empty globs → ERROR
- Catch empty frontmatter values (description:, globs: with no value)
- Fix false positives on empty descriptions (array/whitespace-only)
- Fix 'body starts with description' false positive on empty descriptions
- Updated tests to match new message text (80/80 passing)
