feat: add refactoring label bypass for check_pr_size

PRs with the 'refactoring' label bypass the PR size check, allowing
large but legitimate refactoring PRs. The check_pr_size CLI now accepts
--repo and --pr-number to query PR labels via the Gitea API.

-# DEVX-156: Fix commit message format and release new CI modules
-
-## Problem
-The DEVX-155 merge commit on master has an invalid format
-('DEVX-155: Replace...' missing conventional commit type). This blocks
-the post-merge release workflow's `validate_commit_msg` step, preventing
-`validate_spec`, `check_pr_size`, `nightly_gate`, and `create_dependency_pr`
-from being published to the Gitea PyPI registry. All downstream repos
-(grm, infra, sso-bridge) are blocked — their CI fails with
-`No module named devx.ci.validate_spec`.
-
-## Approach
-Add a trivial user-facing change (version doc comment) with a proper
-conventional commit format to trigger the post-merge release workflow.
-The release will publish the new CI modules that DEVX-155 introduced.
-
-REQ-1: Add a user-facing change to src/devx/ to trigger release
-REQ-2: Ensure the commit message follows conventional format (type: description)
-
-## Test Plan
-- Verify post-merge workflow runs successfully after merge
-- Verify a new release tag is created (v0.51.0 or similar)
-- Verify devx.ci.validate_spec is importable from the published package
-
-## Deploy Plan
-- Merge to master via auto-merge workflow
-- Post-merge workflow auto-releases and publishes
-
-## Rollback Plan
-- Revert the merge commit if release fails
-
-## Acceptance Criteria
-- [x] REQ-1: A user-facing change is added to src/devx/
-- [x] REQ-2: Commit message follows conventional format
