Package a local directory code_source_path for AI Runtime tasks

[ben-hansen-db]

Let ai_runtime_task.code_source_path point at a local directory, not just a pre-built tarball. A new aicode mutator (run in the build phase, before libraries.ExpandGlobReferences/ReplaceWithRemotePath) detects a local-directory value, packages it into a reproducible, content-addressed tarball — honoring .gitignore and the top-level sync.include/exclude globs — uploads it to the user's ~/.air/repo_snapshots directory, and rewrites code_source_path to the uploaded (de-/Workspace-prefixed) path. Because it runs first, PR #5922's artifact-style collection then sees an already-remote path and skips it, so the two compose: a directory is packaged by the CLI, a pre-built .tgz still flows through the artifact path.

Also synthesizes a requirements.yaml next to the task's command_path from the job's serverless environments[] spec, so the AI Runtime harness sets up the workload environment. command_path translation itself is provided by #5922.

Verified end-to-end on a live workspace: a plain bundle deploy of a directory code_source_path yields a job whose run terminates SUCCESS; sync.exclude and .gitignore entries are absent from the uploaded snapshot; unchanged code skips re-upload.
