fix: Replace Codeberg dependency with local Forgejo instance (#611)

- Add setup_forge() to bin/disinto: provisions Forgejo via Docker,
  creates admin + bot users (dev-bot, review-bot), generates API
  tokens, creates repo, and pushes code — all automated
- Rename env vars: CODEBERG_TOKEN→FORGE_TOKEN, REVIEW_BOT_TOKEN→
  FORGE_REVIEW_TOKEN, CODEBERG_REPO→FORGE_REPO, CODEBERG_API→
  FORGE_API, CODEBERG_WEB→FORGE_WEB, CODEBERG_BOT_USERNAMES→
  FORGE_BOT_USERNAMES (with backwards-compat fallbacks)
- Rename API helpers: codeberg_api()→forge_api(), codeberg_api_all()
  →forge_api_all() (with compat aliases)
- Add forge_url field to project TOML; load-project.sh derives
  FORGE_API/FORGE_WEB from forge_url + repo
- Update parse_repo_slug() to accept any host URL, not just codeberg
- Forgejo data stored under ~/.disinto/forgejo/ (not in factory repo)
- Update all 58 files: agent scripts, formulas, docs, site HTML

 - [Claude CLI](https://docs.anthropic.com/en/docs/claude-cli) — `claude` in PATH, authenticated
-- [Codeberg](https://codeberg.org/) account with an API token — disinto reads issues, opens PRs, posts comments, and merges via the Codeberg API
-- A second Codeberg account for the review bot — reviews posted under a separate identity so the dev-agent doesn't review its own PRs (`REVIEW_BOT_TOKEN`)
-- [Woodpecker CI](https://woodpecker-ci.org/) — local instance connected to your Codeberg repo; disinto monitors pipelines, retries failures, and queries the Woodpecker Postgres DB directly
