Subject: [PATCH] feat(workflows): add concurrency control to prevent duplicate
 runs

Added concurrency groups with cancel-in-progress to validate.yml, lint.yml,
and auto-tag.yml workflows.

This ensures that when multiple commits are pushed quickly:
- Only the latest validation/lint run continues
- Older runs are automatically cancelled
- Saves CI minutes and provides faster feedback

Release workflow intentionally excluded (each tag is unique).

Impact: More efficient CI usage, faster feedback on rapid commits.
