Add precommit autofix workflow and patch artifact

[fzyzcjy]

This PR adds a CI remediation flow for generated and normalized file drift, and moves the dev-container automation behind focused frb_internal commands.

• add a standalone Precommit Autofix workflow that produces a downloadable patch artifact instead of forcing contributors to reproduce the full environment locally
• add frb_internal precommit-autofix-in-dev-container to run the autofix flow inside the published dev image
• add frb_internal publish-dev-docker to own the dev image build/smoke-test/publish flow
• keep Dockerfile version parsing as an internal library and remove no-longer-needed CLI/output plumbing
• thin both GitHub workflows so they mainly provide GitHub-specific wiring
• update contributor docs with the current dev image tag and the patch-apply workflow

I did not run tests in this branch.

Code Review

This pull request introduces two new internal tools: dev-docker-metadata for extracting environment versions from Dockerfiles and precommit-autofix for generating git patches when precommit checks detect uncommitted changes. It also updates the contribution documentation and Docker image versions. Several critical compilation errors were identified in PrecommitAutofixService where an undefined method _commandRunner was used instead of the commandRunner field. Additionally, the regex for parsing Dockerfile arguments could be made more robust to handle varying whitespace.
