The share dialog for notes and shared folders now offers "Bearbeiten" and
"Nur Lesen" and stores write/read accordingly. Editors already edit through
the sync engine since phase 2.
Adds e2e/share.e2e.mjs: shares a note as editor through the dialog and checks
that the recipient can edit it; e2e/run.sh runs both browser tests.

Phase 1 of the collaboration plan (server side):
- internal/collab: block tree with parent IDs and fractional order keys,
operations with conflict rules (version check, block leases, conflict
copies instead of lost text, restore on late edits, cycle checks),
in-memory leases/sessions and long-poll notifier.
- Storage: per-note lock + transaction, append-only effect log (doc_ops),
idempotent results per opId (doc_op_results), snapshot, log paging,
central DocRole. Old flat block data is converted to the tree.
- The existing whole-document save (PUT/PATCH) runs as an adapter through
the same engine, so the current editor keeps working and writes to the log.
- API: GET /docs/{id}/snapshot, POST /docs/{id}/sync, GET /docs/{id}/changes
(long poll), POST /docs/{id}/leave; DOC_SEQ poke for WebSocket/SSE rooms.
- Backend accepts editor (write) shares for notes and folders; the forced
read-only migration is gone. The share dialog still offers read only.
- Tests: conflict matrix, order keys, leases, storage adapter round trip,
idempotency, API protocol incl. long poll, and a randomized simulation
(4 clients, lost/duplicated requests and responses, offline phases,
lease expiry) checking convergence, no lost text and exactly-once results.

Remove outdated claims (CRDT, DocRooms, presence, .md files on disk) and
document the actual architecture, API, permissions and known flaws.

Task list shares now carry a permission (editor/viewer). The server rejects
writes from viewers with 403, and the UI hides or disables edit controls
for read-only lists.
