feat(git): thin project onboarding, provider integration, and AgentOS repository access

Effect primitives:
- git-provider: GitProvider, connection states, normalized errors, URL
  normalization, host compatibility, credential freshness window
- git-provisioning: validated Puter commands, migration states, idempotency
  keys, safe replacement rules, owner-safe guards
- git-webhook: supported events, signature verification, delivery states
- host-repository: provider-neutral credential-safe clone via GIT_ASKPASS

Normalized Convex schema:
- gitProviderAccounts, refined gitConnections, gitProviderOrganizations,
  gitRepositories, gitMigrations, gitWebhookDeliveries
- projects: gitRepositoryId + instructions fields
- Schema fields optional for backward compatibility, with backfill cron

Backend:
- Connection health: verify action, hourly reconciliation (covers stale
  active + reauth-required + undefined-state legacy connections)
- Puter provisioning: createPuterUser/Organization/Repository with owner
  binding, startGithubMigration (durable via scheduler), getMigration
- Org ownership: explicit member add with admin role + verification
- Webhook HTTP actions: HMAC verification, delivery persistence with
  idempotency, repository resolution, byte-length payload limit
- Automatic Puter webhook creation after repo creation/migration with
  fail-loud state tracking
- Repository sync after connection (Gitea + GitHub)
- AgentOS execution resolves gitRepositoryId for real clone URL
- Credential gating: state + freshness checks before execution and
  project creation
- listForOrganization for cross-project Work filtering

Frontend:
- /projects onboarding page with GitHub OAuth (linkSocial) and Puter PAT
- Zero-project redirect, repository selection, context editor
- Provider-aware settings panel (no serverUrl for Puter)
- Project selection via ?project= query param
- GitHub scopes: repo + read:org

Agent runtime:
- Clones user repository with GIT_ASKPASS credential helper (no token in
  URL, args, or git config), provider-aware username
- Removed fixed Zopu source path and .env copy

+# Git Provider Setup
+
+This document covers manual setup for GitHub OAuth, Puter Git (Gitea), webhooks, and Convex environment variables.
+
+> **Never place admin or user tokens in checked-in `.env` files or browser variables.** All secrets must be Convex environment variables set via `npx convex env set`.
+
+## GitHub OAuth Application
+
+1. Go to GitHub Settings > Developer settings > OAuth Apps > New OAuth App.
+2. Set the application name (e.g., "Zopu").
+3. Set the homepage URL to your `SITE_URL` (e.g., `https://zopu.cheaptricks.puter.wtf`).
+4. Set the callback URL to `<SITE_URL>/api/auth/callback/github`.
+5. Generate a client secret.
+6. Set Convex environment variables:
+   ```
+   npx convex env set GITHUB_CLIENT_ID <your-client-id>
+   npx convex env set GITHUB_CLIENT_SECRET <your-client-secret>
+   ```
+
+### Requested scopes
+
+Zopu requests `repo` and `read:org`. The `repo` scope grants access to private repositories. `read:org` allows listing organization repositories.
+
+## GitHub Webhook (manual setup for OAuth-based version)
+
+1. Go to the GitHub repository Settings > Webhooks > Add webhook.
+2. Payload URL: `<CONVEX_SITE_URL>/api/git/webhooks/github`
+3. Content type: `application/json`
+4. Secret: generate a strong random string and set it as:
+   ```
+   npx convex env set GITHUB_WEBHOOK_SECRET <your-webhook-secret>
+   ```
+5. Select individual events:
+   - Push
+   - Repository (created, deleted, transferred, renamed, visibility)
+   - Delete
+   - Create
+   - Public
+   - Fork
+6. Do not select "Send me everything."
+
+## Puter Git (Gitea) Admin Token
+
+1. As a Gitea admin, go to Settings > Applications > Generate New Token.
+2. Select scopes: `write:admin`, `write:organization`, `write:repository`.
+3. Set the token:
+   ```
+   npx convex env set PUTER_GIT_ADMIN_TOKEN <your-admin-token>
+   ```
+
+This token is used only for platform administration (user creation, organization creation, repository creation, migration). It is never used for end-user operations.
+
+## Puter Git Webhook
+
+After a repository is created or migrated, Zopu ensures a webhook is configured automatically. If manual setup is needed:
+
+1. Go to the Gitea repository Settings > Webhooks > Add Webhook > Gitea.
+2. Target URL: `<CONVEX_SITE_URL>/api/git/webhooks/puter`
+3. HTTP method: POST
+4. Content-Type: `application/json`
+5. Secret: generate a strong random string and set it as:
+   ```
+   npx convex env set GITEA_WEBHOOK_SECRET <your-webhook-secret>
+   ```
+6. Trigger on: Push events, Repository events.
+
+## Credential Encryption Key
+
+Generate a 32-byte encryption key for AES-GCM credential encryption:
+
+```bash
+openssl rand -base64 32 | base64 | tr -d '\n' | pbcopy
+```
+
+Set it as:
+
+```
+npx convex env set GIT_CREDENTIAL_ENCRYPTION_KEY <base64url-encoded-32-bytes>
+```
+
+The key must be exactly 32 bytes when base64url-decoded.
+
+## Same-Origin Proxy for Better Auth Callbacks
+
+Better Auth requires the callback URL to be on the same origin as `SITE_URL`. If your Convex deployment uses a different origin:
+
+1. Configure a reverse proxy (e.g., Caddy) to forward `/api/auth/*` to the Convex deployment.
+2. Set `SITE_URL` to the proxy origin.
+3. Set `CONVEX_SITE_URL` to the Convex deployment URL.
+
+## Validation Procedures
+
+### Verify a Puter PAT connection
+
+1. Connect a Puter PAT through the UI.
+2. Verify the connection state shows `active`.
+3. List private repositories to confirm token validity.
+
+### Verify GitHub OAuth
+
+1. Click "Connect GitHub" in the UI.
+2. Complete the GitHub OAuth flow.
+3. Verify the connection state shows `active`.
+
+### Reconnection
+
+If a token is expired or revoked:
+
+1. The connection state shows `reauth-required`.
+2. Reconnect the provider through the UI.
+3. The old connection state is updated to `active`.
+4. Projects, repositories, Work, and artifacts are not deleted.
+
+## Environment Variables Summary
+
+| Variable | Required | Description |
+| --- | --- | --- |
+| `SITE_URL` | Yes | Public-facing URL |
+| `CONVEX_SITE_URL` | Yes | Convex deployment URL (may differ from SITE_URL with proxy) |
+| `GIT_CREDENTIAL_ENCRYPTION_KEY` | Yes | Base64url-encoded 32-byte AES-GCM key |
+| `PUTER_GIT_ADMIN_TOKEN` | Yes | Gitea admin token for provisioning |
+| `GITHUB_CLIENT_ID` | For GitHub | OAuth app client ID |
+| `GITHUB_CLIENT_SECRET` | For GitHub | OAuth app client secret |
+| `GITHUB_WEBHOOK_SECRET` | For GitHub webhooks | HMAC verification secret |
+| `GITEA_WEBHOOK_SECRET` | For Puter webhooks | HMAC verification secret |
+| `FLUE_DB_TOKEN` | Yes | Private agent backend token |
+| `FLUE_URL` | Optional | Private agent backend URL |
+| `NATIVE_APP_URL` | Optional | Native app deep-link scheme |
