Tagging an existing file/folder emits only OCP\SystemTag\MapperEvent — never a
Node*Event — so tagged PDFs were previously only picked up by the hourly
scanner. Subscribe to the tag event and reconcile membership so adding/removing
the `vector-index` tag (re)indexes in near-real time.
- webhook_presets: add OCP\SystemTag\MapperEvent to the files_sync preset
(NC 32+, where MapperEvent gained getWebhookSerializable(); harmless on older
servers — it just never fires).
- webhook_parser: parse MapperEvent (objectType=files) into a path-less file
"reconcile" task. The payload carries only a fileid + tagIds (no name/path),
so assign and unassign both collapse to a reconcile.
- processor._reconcile_tag_event: resolve the fileid against the user's current
vector-index PDFs (find_files_by_tag). Present -> index with the resolved
path/etag; absent -> flip to delete. Naturally handles "an unrelated tag
changed" and a tagged folder's own fileid (no-op; the scanner still expands
folders to descendants).
- Unit tests for the parser branch and the reconcile.
The matching admin-UI preset change ships separately in the astrolabe app repo.

Adds optional shared-secret authentication for /webhooks/nextcloud,
addressing the security follow-up flagged in #747.
Behavior:
- WEBHOOK_SECRET set: registrations pass authMethod="header" with
authData={"Authorization": "Bearer <secret>"} (encrypted at-rest in
Nextcloud's DB and forwarded on every delivery). The receiver
validates the same header with hmac.compare_digest before parsing
any payload; missing/invalid → 401.
- WEBHOOK_SECRET unset: registrations stay on authMethod="none" and
the receiver accepts unauthenticated POSTs (logging a one-time
startup warning). Backward compatible — operators can roll out at
their own pace.
Implementation notes:
- WebhooksClient.create_webhook gains an `auth_data` parameter mapped
to NC's `authData` body field; this is distinct from the existing
`headers` parameter (`headers` is plaintext static request headers,
`authData` is encrypted at-rest in NC and only emitted when
authMethod="header"). The previous `auth_method="bearer"` mention in
the docstring was incorrect — NC supports only "none" and "header".
- A small `webhook_auth_pair()` helper in auth/webhook_routes.py
centralises the secret→(auth_method, auth_data) resolution so the
preset flow and the Astrolabe-facing /api/v1/webhooks endpoint stay
in sync.
Also addresses the smaller review points from #747:
- f-string → lazy %s formatting in webhook_receiver.py and
webhook_routes.py.
- Move `int(time)` inside webhook_parser's try/except so a malformed
`time` field returns None instead of raising ValueError.

The /webhooks/nextcloud endpoint was a no-op stub that logged the
payload and returned 200 OK; webhook deletions never reached Qdrant.
Compounding that, _get_webhook_uri() registered the docker-compose
internal hostname (http://mcp:8000) with Nextcloud whenever
/.dockerenv existed — including ECS Fargate — so cloud deployments
were registering a URL NC could not resolve.
- New vector/webhook_parser.py extracts a DocumentTask from
NodeCreatedEvent / NodeWrittenEvent / BeforeNodeDeletedEvent
payloads scoped to */files/Notes/*.md (matching the registered
preset filters).
- New vector/webhook_receiver.py pushes that task onto the same
send-stream the scanner uses (app.state.document_send_stream),
with 503 when sync is not running so NC retries delivery.
- _get_webhook_uri() now prefers NEXTCLOUD_MCP_SERVER_URL over the
/.dockerenv branch, so the explicit public URL set on cloud tasks
wins; docker-compose dev still falls back to the internal name when
no public URL is configured.
Calendar / Tables event parsing is intentionally out of scope here.
