feat(ci): add IR version consistency validation and fix mismatches

[jsklan]

Description

Adds CI validation to ensure irVersion consistency between seed.yml and versions.yml files, and fixes all existing mismatches found in the codebase.

The original validation script from Devin was simplified from 131 to 61 lines, removing verbose formatting and following the project's patterns of keeping validation logic simple and focused.

Changes Made

• Validation Script: Added scripts/validate-ir-version-consistency.sh with simplified logic for checking irVersion consistency
• CI Integration: Added GitHub Actions workflow that runs validation on relevant file changes
• Deprecated Generator Exclusion: Script skips ruby v1 generators (ruby-model, ruby-sdk) as they are deprecated
• Seed Configuration Fixes: Updated 5 seed.yml files where version was lower than latest release:
  • fastapi: 60 → 61
  • go-fiber: 58 → 60
  • pydantic-v2: 60 → 62
  • pydantic: 60 → 62
  • rust-sdk: 61 → 62
• Generator Releases: Published new patch versions for generators where seed was ahead:
  • go-sdk v1.22.9 with irVersion 61 (to support Generation Metadata feature)
  • rust-model v0.1.2 with irVersion 61

Testing

• Manual testing completed - script correctly identifies and resolves all mismatches
• Validation now passes with all IR versions consistent across the codebase
• Script handles edge cases (missing files, deprecated generators)
