Developer hooks and filters

Extend documented seams without bypassing endpoint authorization or transaction boundaries.

Supported extension points

Hook	Purpose
`drecha_forms_entitlements`	Filter the feature map; it does not replace endpoint authorization
`drecha_forms_submission_payload`	Filter normalized data before the entry transaction
`drecha_forms_entry_created`	Observe a newly committed entry
`drecha_forms_plan_premium_automations`	Add durable, entitled post-submission jobs
`drecha_forms_handle_extension_job`	Handle a claimed extension job through the shared worker
`drecha_forms_spam_result`	Filter the bounded spam result after built-in checks

Keep pre-commit submission filters deterministic and fast. Queue slow or external work only after the entry commits. Administrative REST operations still require authentication, capabilities, and nonces; Pro Bearer tokens remain scoped, hashed, and revocable.
