Adds sync-webhook-events.yml, a sibling of sync-asyncapi.yml for the server webhooks module. It runs hourly at :45, apart from the asyncapi sync's :15. Each run:

1. Adds new event types. npm run sync:webhooks appends to scripts/webhook-event-types.json every event type in the webhooks section of https://app.base44.com/api/v1/outbound-webhooks/openapi.json. It only adds: a retired type leaves the spec, but endpoints that selected it keep receiving it, so the SDK keeps its type.
2. Regenerates every type. npm run generate:webhooks regenerates webhooks.events.generated.ts from https://base44.com/webhooks/schemas on every run, so a changed schema is picked up even when the list didn't change.
3. Keeps one rolling PR. On a change it builds the docs, runs the tests, and opens or updates the PR on bot/platform-webhook-events-sync. With no change, it closes a stale one. This is the same mechanics as the asyncapi sync.

Two changes so the bot's PR passes without hand edits:

• Exports: src/server/index.ts re-exports every generated data type with export type * instead of naming each one. Before this, a new event's type wasn't exported, and TypeDoc (treatWarningsAsErrors) failed the docs build.
• Type test: tests/types/webhooks.types.ts no longer pins the full list of known types in its default branch. It also drops owner_service_external_id from the app.created.v1 fixture: that field was removed from every event in base44-dev/apper#30148.

The first run, verified locally, will:

• add builder.turn_started.v1 and builder.turn_ended.v1;
• remove owner_service_external_id from the existing events, matching the published schemas.

That's both an added event and an edited one. I ran the workflow's steps against prod: the sync, the generation, create-docs and npm test (82 passed). This PR leaves those changes to the bot, so its first PR proves both paths.
