Notion PR status sync action (TS rewrite)

[vatsalpatel]

Rewrites the action to sync Notion Status from PR lifecycle events (replacing the old title-prefix + Make-webhook behaviors tied to the native integration that's being removed).

What it does

• On PR events, updates the PR's row in the Notion Pull Requests DB (Draft / Open / Merged / Closed) and the linked issue's Status (opened→In PR, changes_requested→Fixes Required, merged→For QA — only when the last linked PR merges).
• Resolves the issue by PR URL → Pull Requests DB relation, with an [ISSUE-N]-in-body fallback. No title marker needed (conventional-commit safe).
• Non-fatal (never reds a check) + idempotent. using: node20, ncc-bundled dist/.

Also included

• status/ — standalone Python composite action (feature parity, separate).
• Part 1 groundwork: open-pr skill + link_pr.py; OpenSpec change link-pr-to-notion.

⚠️ How to test — do NOT merge to main to test

~20 repos pin notion-issue-sync@main, so merging flips the whole fleet at once. Test this from the branch ref first in a single repo:

on:
  pull_request: { types: [opened, reopened, ready_for_review, closed] }
  pull_request_review: { types: [submitted] }
jobs:
  notion:
    runs-on: ubuntu-latest
    steps:
      - uses: MathGaps/notion-issue-sync@notion-status-action
        with:
          notion_token: ${{ secrets.NOTION_TOKEN }}

Only merge to main once you're happy and ready to roll it out everywhere.

Known: CI may be red

check-dist / build-test still pin node16 and lint the removed inputs — cosmetic, doesn't affect the action (it runs from the committed dist/). Follow-up: bump those workflows to node20.
