ci: sync RFP proposals to tracking board (#17)

[hackyguru]

What

GitHub Actions workflow that keeps org project #17 (RFP & LPrize Tracking) in sync with proposal issues:

• Label proposal → add to board as Received Proposals — only if the issue isn't already on the board in another column (never overrides an existing status).
• Label under-review → move to Priority review (always).

Why

Proposals should surface on the tracking board automatically, giving leadership live visibility without manual board upkeep.

How it works

• Trigger: issues: [labeled], gated to proposal / under-review.
• Resolves the project, Status field, and target option by name at runtime, so it survives Projects option-ID regeneration.
• Checks the issue's existing board item/status first; addProjectV2ItemById is idempotent (no duplicates).
• Add-only: removing a label does nothing (by design).

Required setup (before it works)

Add repo secret PROJECTS_PAT:

• Classic PAT with repo + project, or
• Fine-grained PAT with Organization projects: Read & write + Issues: Read for logos-co.

The default GITHUB_TOKEN cannot write to org-level Projects v2, hence the PAT.
