feat: wire Forgejo Actions CI/CD workflows (#22)
- ci.yml: API lint (ruff F+I) + pytest, web vue-tsc + vitest + build
- mirror.yml: push to GitHub (CircuitForgeLLC) + Codeberg (CircuitForge) on main/tags
- release.yml: Docker build → Forgejo registry + release via API; GHCR deferred pending BSL policy (cf-agents#3)
- .cliff.toml: git-cliff changelog config for semver releases
- pyproject.toml: add [dev] extras (pytest, ruff), ruff config
- Fix 45 ruff violations across codebase (import sorting, unused vars, unused imports)

"""Snipe feature gates. Delegates to circuitforge_core.tiers.
Tier ladder: free < paid < premium
Ultra is not used in Snipe — auto-bidding is the highest-impact feature and is Premium.
BYOK unlock analog: LOCAL_VISION_UNLOCKABLE — photo_analysis and serial_number_check
unlock when the user has a local vision model (moondream2 (MD2) or equivalent).
Intentionally ungated (free for all):
- metadata_trust_scoring — core value prop; wide adoption preferred
- hash_dedup — infrastructure, not a differentiator
- market_comps — useful enough to drive signups; not scarce
- scammer_db — community data is more valuable with wider reach
- saved_searches — retention feature; friction cost outweighs gate value
