fix(version-extraction): support date-based version numbers

Problem:
- ruby-build shows blue ? instead of green ✅ despite versions matching
- Snapshot shows latest_version: '' (empty string)
- extract_version_number() regex requires dots, fails on date versions

Root cause:
- Regex pattern \d+(?:\.\d+)+ requires at least one dot
- Date-based versions like '20251023' have no dots
- Version extraction fails, returns empty string
- Status becomes UNKNOWN instead of UP-TO-DATE

Solution:
- Change regex from \d+(?:\.\d+)+ to \d+(?:\.\d+)*
- Makes dots optional (zero or more instead of one or more)
- Now supports both formats:
  - Semantic: 1.2.3, 1.2.3.4
  - Date-based: 20251023, 20250822

Impact:
- ruby-build: 20251023 === 20251023 (green ✅)
- parallel: 20250822 detected correctly
- All dotted versions still work (1.2.3, etc)

Verification:
- Tested: 20251023, v20251023, 1.2.3, v1.2.3, ruby-build-20251023
- All extract correctly with new regex
- Status determination now accurate for date-based tools
