Portfolio standards baseline

[projectious]

Implement the portfolio standards review findings: retain the MIT license and README; add lifecycle marker, CONTRIBUTING.md, SECURITY.md, manual local build/deploy/rollback and no-GitHub-Actions guidance; enforce canonical Git identity; publish privacy/data-handling and asset/IP provenance guidance. Acceptance: public-facing content has documented rights and operating procedures.
