feat: 15 logic component Workers + cypher-executor auth/credentials routing

Component Workers:
- Deploys if_control, switch, filter, merge, try_catch, wait, set,
  array_ops, string_ops, number_ops, date_ops, validate_json,
  ai_transform_compile, ai_transform_run, foreach_control as
  independent Workers, backing cypher-executor's SVC_* service
  bindings (fast internal RPC for logic components).

cypher-executor routing:
- New routes: /auth (recipe resolution), /credentials (CRUD),
  /webhooks/named (user-friendly alias for cmp_/rec_ hashes).
- auth-recipe-seeds.ts: 20 pre-built platform auth recipes
  (Google Sheets, Gmail, Telegram, etc.) seeded into RECIPES KV.
- graph-executor + cypher-handlers + search-nodes updated for
  the new resolution chain.
- scripts/seed-auth-recipes.ts: one-shot tool to push seeds to KV.
- wrangler.toml: 15 SVC_* bindings wired to the new logic Workers.
