chore: delete dead auth/github stub routes

[sweetmantech]

Summary

• Delete the three app/api/auth/github/* and app/api/auth/signin/github route handlers
• All three are leftovers from the Better Auth + linked-accounts flow that PR feat(db-unification): point open-agents at recoupable Supabase #26 ripped out — they only redirect, and their redirect targets no longer exist:
  • auth/github/callback → /
  • auth/signin/github → /api/auth/signin/vercel (404)
  • auth/github/reconnect → /api/github/app/install (404)
• Nothing in the app links to them; the OAuth flow they used to serve is replaced by Privy. The reconnect test asserted a redirect into a non-existent install route, so it goes too.

This is Phase A of the open-agents /api/ → api codebase migration (overall direction: api owns all backend, open-agents UI calls api over Privy Bearer; later folded into chat).

Test plan

• bun run --cwd apps/web typecheck passes (no callers)
• bun run check passes (no lint/format issues)
• Grepped repo for auth/github, auth/signin/github, github_reconnect, /api/github/app/install — zero hits outside the deleted files
• Vercel preview boots and /sessions still loads for an authenticated user

Summary by cubic

Removed dead GitHub auth routes apps/web/app/api/auth/github/{callback,reconnect} and apps/web/app/api/auth/signin/github, plus the reconnect test. They only redirected to missing endpoints and are obsolete after the Privy auth flow; this is Phase A of moving open-agents /api/ into the api codebase.

^{Written for commit 7bb1053. Summary will update on new commits.}

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

🐰 Four routes hop away, auth flows rearrange,
GitHub callbacks fade to silence and change,
Reconnect and signin dance off the stage,
The auth saga turns a cleaner, simpler page! 🔐✨
