chore: adopt vYYYY.MM.DD.HHMMSS.COMMIT versioning scheme

Change from v0.1.YYYYMMDD.HHMMSS.COMMIT to vYYYY.MM.DD.HHMMSS.COMMIT
to align with BizPrint versioning style:
- Semantic year.month.day separation via dots
- Preserves hourly precision (HHMMSS)
- Includes commit hash for traceability

Example: v2026.07.24.165410.7bd491e
