fix(marketing): deploy site with nightly releases

[t3dotgg]

Marketing site updates wait for manual deployments because automatic Git deployments are disabled.

Deploy pinglabs/t3code-marketing after each successful nightly release, using the release commit and existing Vercel credentials. Stable releases do not deploy the site because they can promote an older nightly commit.

Validated YAML, formatting, shell syntax, and mocked deployment behavior for project lookup, production deployment, scope overrides, missing credentials, and API failures. No live deployment was run.

Created with GPT-6 Astra in Codex.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This adds an automatic GitHub Actions job that deploys the marketing site to Vercel production after each successful nightly release, using production credentials and a live project lookup. Because it materially expands production deployment behavior, the change warrants human review.

Not approved because:

• Monthly spending limit reached (workspace setting). Approvability relies on correctness review in order to determine eligibility
