feat: Function triggers — schedule, inbound hook, domain events

Migration 00016: function_id on scheduled_jobs/inbound_hooks,
event_pattern on functions, 'event' in the run-trigger enum.

- Jobs deliver to a function instead of HTTP when function_id is set;
  the run's status_code mirrors the process exit code. Clearing the
  field returns the job to URL delivery.
- Inbound hooks gain mode "function" — received body becomes stdin
  payload, acked immediately, run recorded async.
- event_pattern (document.*, *, exact type) fires the function detached
  on matching publishEvent — never blocks realtime/webhook fan-out.
- One executeFunction path serves manual/schedule/hook/event; run rows
  record the trigger source.
- Backend image now ships bun 1.3.14 so Functions work under compose.

Dashboard: job target picker, hook function mode, event-pattern field.

Verified live: job run → success (status_code 0), hook POST → run,
document.created → event run with correct payload.

 - **Email templates + send log** (`core.email_log`, migration 00014) — the mailer renders registered templates (currently `invitation`) and every send — successful or failed — is recorded with template, recipient, subject, status, and error text. `GET /projects/:id/emails` lists recent sends; the Members page shows an "Email log" card under pending invitations.
 - **S3-compatible object storage backend** — `BACKEND_STORAGE_DRIVER=s3` swaps the local disk store for any S3-compatible API (AWS, MinIO, Garage, R2) via a stdlib-only SigV4 implementation — no AWS SDK dependency. `S3_ENDPOINT`/`S3_REGION`/`S3_BUCKET`/credentials configure it; `S3_PATH_STYLE` (default on) covers MinIO/Garage, off for AWS virtual-hosted. The configured bucket is created on startup if missing; objects stream with computed SHA-256, `storage_path` records `s3://bucket/key`. Verified live end-to-end (bucket → put → get → copy → list → delete).
 - **Functions** (`core.functions` + `core.function_runs`, migration 00015) — project-scoped JS/TS executed by a runtime binary on the backend host (`bun` or `deno`, per function). The JSON payload arrives on stdin and as `PRIMORA_PAYLOAD`; stdout/stderr are captured per run (capped at 64 KiB) with status, exit code and duration — `FUNCTIONS_RUNTIME`/`FUNCTIONS_TIMEOUT_SECONDS`/`FUNCTIONS_MAX_OUTPUT_BYTES` configure the runner. API: CRUD under `/projects/:id/functions`, `POST …/invoke` (502 + recorded run on failure), `GET …/runs`. Dashboard gains a Functions page: code editor, JSON payload invoke, live result, run history. Code executes with backend privileges — the documented self-hosted trust model.
+- **Function triggers** (migration 00016) — three new ways to run a function, all through the same executor and run log. Scheduled jobs accept `function_id` instead of `url` (run status mirrors the exit code); inbound hooks gain `mode: "function"` — the received body becomes the function's stdin payload, acked immediately with the run recorded async; and `event_pattern` on a function (`document.*`, `*`, or an exact type) fires it detached whenever a matching domain event publishes — `{event, project_id, occurred_at, data}` as payload. Runs record trigger source: `manual`/`schedule`/`hook`/`event`. Dashboard: function event-trigger field, job target picker (URL or function), and inbound-hook function mode.

 ## Storage constraint
 
-Object storage is the **local filesystem** (`backend_storage` volume). There
-is no S3-compatible backend yet — the volume must be on durable, backed-up
-disk, and a single host serves all objects. Plan capacity accordingly;
-multi-node deployments need an external object store first.
+Object storage defaults to the **local filesystem** (`backend_storage`
+volume) — durable, backed-up disk on a single host. For multi-node or
+external object stores set `BACKEND_STORAGE_DRIVER=s3` + the `S3_*`
+variables above (AWS, MinIO, Garage, R2 all work).
+
+## Functions trust model
+
+Function code runs as a child process of the backend — same host, same
+privileges, no sandbox. Treat every project member who can edit a function
+as holding a shell on the backend host. If that is unacceptable for your
+deployment, do not enable untrusted editors; isolated runtimes are on the
+roadmap.
