add OpenRouter proxy for managed model routing and OSS program (#488)

* add OpenRouter proxy for managed model routing and OSS program

proxy layer that mints ephemeral OpenRouter keys for users without BYOK
API keys. two paths: pro plan users get their selected model proxied via
OpenRouter; OSS program repos (hard-coded allowlist in config.ts) get
free Claude Opus. BYOK env vars (PULLFROG_MODEL/OPENCODE_MODEL) always
take precedence.

frontend: OSS repos see a static "Opus (Free)" badge with the model
dropdown disabled and no API key requirement. all models now carry
openRouterResolve metadata for proxy target resolution.

Made-with: Cursor

* implement OSS program: proxy infrastructure for free model credits

server-side OSS allowlist determines eligible repos. action mints
ephemeral OpenRouter keys via OIDC-authenticated /api/proxy-token
endpoint (idempotent on runId, $10 per-key safety limit). keys are
disabled on workflow completion when no running refs remain. HWM-based
usage sync tracks cumulative spend per account.

schema: ProxyKey model, Account.usageUsd/activeKeyId, WorkflowRun.proxyKeyId
action: OIDC credential stashing, resolveProxyModel uses server oss flag
frontend: isOss flows from server page to components (no client allowlist)
Made-with: Cursor

* address PR review: repo cross-check, key retirement lifecycle, dead code removal

- proxy-token: verify runId belongs to OIDC-authenticated repo via repo relation
- add retireKey() shared primitive: disable in OpenRouter first, then mark disabled in DB
- rotateKey: retire old active key after swap to prevent orphans
- webhook: replace inline cleanupProxyKey with retireKey calls
- syncAccountUsage: skip disabled keys
- remove vestigial AccountPlan/plan field from action types
- add disabled field to ProxyKey schema + migration

Made-with: Cursor

* replace deprecated opencode/mimo-v2-flash-free with mimo-v2-pro-free

Made-with: Cursor

* fix migration ordering: rename disabled migration to sort after table creation

Made-with: Cursor

* squash proxy key migrations into single migration

Made-with: Cursor

* add preview repo to OSS allowlist for testing

Made-with: Cursor

* populate OSS allowlist from oss-program-invitees.json

Made-with: Cursor

* format oss-program-invitees.json

Made-with: Cursor

* add installed public repos to OSS allowlist

split ossRepos into three provenance-tracked lists:
- internalRepos (pullfrog, colinhacks, RobinTail)
- installedPublicRepos (external public non-fork repos with active installs)
- invitees (from oss-program-invitees.json)

also adds scripts/list-oss-candidates.ts to regenerate the installed list

Made-with: Cursor

* fix: resolve tokens before clearing OIDC env vars

resolveTokens → acquireNewToken → isOIDCAvailable() checks
ACTIONS_ID_TOKEN_REQUEST_URL/TOKEN env vars. The new OIDC
stashing code was deleting them in restricted shell mode before
resolveTokens ran, causing it to fall through to the GitHub App
path which requires GITHUB_APP_ID/GITHUB_PRIVATE_KEY.

Made-with: Cursor

* derive proxy-token auth from OIDC claims, add ensureWorkflowRun upsert

- proxy-token no longer requires body.runId; uses claims.run_id + claims.repository
- shared ensureWorkflowRun upsert called from both webhook and proxy-token
- workflow_run_requested handler now eagerly creates WorkflowRun records
- eliminates race condition between webhook and action proxy-token call

Made-with: Cursor

* hardcode PULLFROG_ACCOUNT_ID, document preview debugging lessons

GitHub node IDs are constant — no reason for this to be an env var.
Removes the trailing-newline bug that caused P2025 errors.
Adds wiki docs on workflow testing, Vercel env gotchas, and Neon
preview branch discovery.

Made-with: Cursor

* fix: parse OpenRouter create-key response correctly

the API returns `key` at the top level, not inside `data`

Made-with: Cursor

* onboarding cards, unlock OSS model selection, simplify console

- add OnboardingCard component with two states: workflow install
  and model+test (dispatches "Tell me a joke" for test run)
- replace PromptBox overlay gates with dedicated onboarding cards;
  PromptBox is now just the form, always enabled
- use hasWorkflowRuns DB check to decide onboarding vs promptbox
- unlock ModelSelector for OSS repos (was locked to Opus badge);
  resolve proxyModel from repo's selected model alias in run-context
- rename "API key" row to "Model costs" with pure client-side states:
  OSS covered, auto-resolve, free model, BYOK with env var names
- add "(Recommended)" badge to model aliases with recommended: true
- remove OSS_MODEL_DISPLAY_NAME constant and secrets-fetching logic

Made-with: Cursor

* update stale xai model snapshot

Made-with: Cursor

* rename Permissions to Security, hide git push toggle, add shell isolation toggle with disabled state for public repos, remove opentoad agent name from logs

Made-with: Cursor

* chevron hover states, sidebar hooks/security entries

Made-with: Cursor

* address PR review feedback: rename recommended→preferred, fix dispatch orphan, update wiki docs

- rename `recommended` to `preferred` in model alias registry to distinguish
  from the UI "Recommended" badge (which is hardcoded for opus + codex only)
- cancel precreated WorkflowRun when workflow lookup fails in dispatch-workflow
- replace run_sql/vercel env pull in wiki docs with neonctl + Prisma pattern
- extend scripts/neon-branch.ts to output DATABASE_URL via neonctl
- add Recommended badge to GPT Codex alongside Claude Opus in ModelSelector
