Add trusted base branch workflow policy

[justin808]

Why

The repository does not currently declare its trusted base branch for the agent workflow. Add the minimal trusted-base policy needed for guarded PR processing.

What changed

• Added .agents/agent-workflow.yml.
• Declared base_branch: main and no other policy keys.

Validation

• YAML parses exactly as { "base_branch": "main" }.
• git diff --check passes.
• Independent checker confirmed the commit is a single-parent child of pinned base cbd68a19ea770ab0637756cecee4a3c74038c212 and changes only the authorized file.
• Stage dependency gate replay is eligible for exact head 750b07f7d458e53eb194bf357b617bcfbe0f6f61, with trusted plan binding sha256:e2164d4c9e1521e0c0a09cffcf164542f4d53da027c89b396d1d4d4333b3e91f.

Merge confidence

This is a two-line policy bootstrap with code-only rollback: revert the merge commit to remove the policy file.
