b8fba8195f feat(ingestion): metadao.fi scraper to replace broken futard.io ingestion
Some checks failed
CI / lint-and-test (pull_request) Has been cancelled
Background:
- futard.io retired its /api/graphql endpoint between Apr 17–20
- Cloud Scheduler ingest-futard has been firing into 500s ever since
  (the AttributeError on e.url masked the real 404 for 5 days; fixed
   in living-ip/teleo-api@b8eb441 which surfaced the actual root cause)
- The ecosystem migrated to metadao.fi, which is Vercel-protected
- Direct curl is blocked by Vercel's anti-bot challenge regardless of
  headers; a real headless browser passes it cleanly

Approach:
- Playwright-driven scraper, runs as a one-shot
- Discovery: scrape /projects DOM for project slugs, then each
  /projects/{slug} for proposal addresses
- For each NEW proposal: visit page for prose body + call
  /api/decode-proposal/{addr} via in-browser fetch (bypasses challenge
  via the primed Vercel cookies in the browser context) for structured
  on-chain instructions
- Idempotent: dedup against existing proposal addresses in archive
  frontmatter AND filename basenames
- Filename embeds 8-char address fragment for stable cross-run dedup
  even on projects that don't use DP-NNNNN naming convention

Tested locally against 6 active projects (p2p-protocol, paystream,
zklsol, loyal, ranger, solomon). Captured 13 new proposals — including
the Solomon Gigabus DP-00003 that triggered this work — with proper
titles, status, on-chain instruction decoding (Squads transactions,
SPL transfers, memos), and project metadata.

Output schema matches existing futardio source files (type: source,
event_type: proposal, domain: internet-finance, status: unprocessed)
so the existing extract pipeline picks them up unchanged.

Architectural note: this script is intentionally NOT wired to systemd
yet — VPS deploy needs Playwright + Chromium system libs which require
apt sudo (currently scoped to teleo-* services only). Reviewing the
script first; deploy path is a separate decision.
