fix(version): make version programmatic by reading from deno.json

- Replace hardcoded version in 00_commitinfo_data.ts
- Now dynamically imports deno.json and reads version
- Version will auto-update when deno.json is changed
- Fixes version showing 3.1.2 instead of 4.0.0

test: add Docker test scripts for v3→v4 migration
- 01-setup-v3-container.sh: Creates systemd container with v3
- 02-test-v3-to-v4-migration.sh: Tests migration (now fixed)
- 03-cleanup.sh: Removes test container
- README.md: Complete documentation

Tested: Version now correctly shows 4.0.0
