Replaces the mana-sync event-stream export (GET /backup/export) with a
fully client-driven `.mana` v2 archive: webapp reads Dexie, decrypts
per-field, packages JSONL + manifest, optionally PBKDF2+AES-GCM seals
with a passphrase.
- New: backup/v2/{format,passphrase,export,import}.ts + format.test.ts
(10 tests: round-trip, sealed path, 3 failure modes incl. wrong-
passphrase vs. tamper distinction).
- UI: ExportImportPanel with module multi-select, optional passphrase,
progress + sealed-file detection — replaces the old backup flow in
Settings → MyData.
- Removes services/mana-sync/internal/backup/ and the corresponding
client helpers + v1 tests. No parallel paths, no legacy shim.
- Why client-driven: zero-knowledge users hold their vault key only
client-side, so a server exporter cannot produce plaintext archives;
GDPR Art. 20 portability is better served by plaintext-by-default.
- Cross-account restore works via re-encryption under the target
vault key (no MK transfer needed).
DATA_LAYER_AUDIT.md §8 rewritten to reflect the new architecture.

Closes the gap between "invite flow UI exists" and "two users in the
same space actually see each other's data". Three pieces land together
because they're meaningless without each other.
mana-auth — new internal endpoint:
GET /api/v1/internal/users/:userId/memberships
Returns [{organizationId, role}, ...] for the user. mana-sync uses
this to populate the multi-member RLS session config.
mana-sync — membership lookup:
new internal/memberships package with an HTTP client + 5 min
per-user cache, fail-open (empty list = pre-Spaces behavior).
Config gets MANA_AUTH_URL (default http://localhost:3001).
Handler.NewHandler takes the Lookup. Every Push/Pull/Stream call
now passes spaceIDsFor(userID) to Store methods.
GetChangesSince + GetAllChangesSince extend their WHERE clause:
WHERE (user_id = $1 OR space_id = ANY($memberSpaces))
so co-members see each other's rows, not just the author.
apps/web — encryption skip for shared-space records:
encryptRecord now checks record.spaceId:
- `_personal:<userId>` sentinel OR no active shared space → encrypt
with user master key (E2E as today).
- Active space resolves to non-personal type AND spaceId matches
that space → skip encryption; write lands plaintext.
decryptRecord is unchanged because its per-field isEncrypted() guard
already passes plaintext through.
Phase-1 compromise: shared-space data is protected by server RLS
only, not E2E. Phase 2 adds per-Space shared keys with per-member
wrap — tracked in docs/plans/spaces-foundation.md.
Plus docs/plans/shared-space-smoketest.md: step-by-step Zwei-User-Test
mit erwarteten Ergebnissen und Debugging-Hinweisen bei Problemen.
Build + go test + web check all green.

Recovering three files dropped when a parallel terminal reset past the
original M1 commit:
- cmd/server/main.go: register GET /backup/export outside billingMiddleware
- lib/api/services/backup.ts: browser-side downloadBackup() helper
- settings/my-data/+page.svelte: "Backup & Wiederherstellung" section
Pairs with the earlier backup handler + schema_version work already on
main (79996f946). With this commit the endpoint is actually reachable
end-to-end and the download button works.

New endpoint GET /sync/{appId}/stream sends Server-Sent Events with
change data directly, replacing the WebSocket notification + HTTP pull
round-trip pattern.
Server (Go):
- HandleStream() in handler.go: SSE endpoint with initial sync + live streaming
- Hub.Subscribe()/Unsubscribe() in hub.go: channel-based SSE subscriber system
- Notification type for type-safe SSE events
- convertChanges() helper extracted from duplicated code
- WriteTimeout set to 0 for SSE long-lived connections
Protocol: Client connects to /sync/{appId}/stream?collections=a,b&since=...
Server sends initial changes, then streams live changes as other clients sync.
Heartbeat every 30s keeps connection alive. Push still uses POST /sync/{appId}.
WebSocket remains available as fallback (not removed).

Add unified /ws endpoint that serves all app notifications over a single connection.
The server now includes appId in the sync-available message payload so the client
knows which app to pull. Legacy /ws/{appId} endpoint remains for backward compatibility.
Backend (Go):
- hub.go: Message struct gains AppId field, NotifyUser sends to all user clients
(unified clients receive everything, legacy clients filtered by appId)
- main.go: new GET /ws route (empty appId = unified mode)
Frontend (sync.ts):
- Single connectUnifiedWs() replaces 27 per-app connectWs() calls
- Parses msg.appId from server to pull only the affected app
- Reconnect/offline logic simplified to one WS
This reduces WebSocket connections from 27 per user to 1, cutting server
connection overhead by ~96%.

Implement the foundational local-first data layer for ManaCore apps:
- New @manacore/local-store package (Dexie.js IndexedDB, sync engine, Svelte 5 reactive queries)
- New mana-sync Go service (sync protocol, WebSocket push, field-level LWW conflict resolution)
- Todo app migrated as pilot: stores read/write IndexedDB, guest mode with onboarding seed data
- PillNavigation: prominent login pill for unauthenticated users
- SyncIndicator component showing local/syncing/offline status
- GuestWelcomeModal on first visit for Todo app
- Removed demo-mode auth_required checks from Todo components (all writes are now local)
- CSP fix for local development (localhost:3001, localhost:3050)
