feat: make autonomous development factory the beginner default

[cskwork]

What changed

• Adds a beginner factory CLI: init, sync, and start.
• Makes Ready -> Build -> Verify the minimal default while preserving the prior workflow under examples/advanced.
• Imports the complete Supergoal Wayfinder dependency graph idempotently.
• Runs every ticket through the Supergoal delivery ledger, with SuperPM for customer research/spec work, Superdesign for design work, and SuperQA for browser verification.
• Enforces Build and Verify contracts before terminal delivery, including stale-worker reconciliation.
• Auto-commits and auto-merges only after exact verification evidence passes.

Why

This gives beginners one understandable autonomous software-development loop while keeping customization points explicit. It does not promise profitability; SuperPM provides demand evidence and the product still has to earn revenue in the market.

Proof

• Full suite: 1474 passed, 5 skipped.
• Focused factory/runtime suite: 456 passed, 3 skipped.
• Ruff: pass.
• Pyright: 0 errors, 0 warnings.
• Doctor: pass.
• Wheel build: pass with factory assets and no bytecode.
• Real OpenCode generated-project run: Ready -> Build -> Verify -> Done; scoped two-file commit 1e6bf5c; automatic merge 9fe55bf; exact unittest passed.

Review notes

The final adversarial pass closed two delivery bypasses: terminal transitions and stale terminal reconciliation now run the same refreshed contract gate. The factory Verify table requires one literal pass row per declared acceptance criterion and rejects extras.
