Phase 3 of the collaboration plan:
- Blocks held by someone else show a lock with the name and are read-only;
Enter in such a block adds a new block below. Delete, merge, indent and
drag are not started when a involved block (or one in its branch) is
locked; a short notice explains why (fixes FLAW-25).
- Presence: the editor header lists who else has the note open.
- Conflict copies are highlighted ("Konflikt – Version von …") with
Übernehmen (replaces the original or the title) and Verwerfen. Both check
the locks of the original and of the copy first.
- Undo/redo of own changes (Ctrl/Cmd+Z, Ctrl+Shift+Z, Ctrl+Y, beforeinput
history events): typing is grouped per block until a 1 s pause, up to 200
steps per tab; a step is skipped with a notice if someone else changed or
holds the block meanwhile. New clearConflict props patch on the server.
- New blocks get focus synchronously on mount (fixes FLAW-26).
- Fix: after reopening a note from local storage the engine polled every
30 s instead of 3 s until the next change, because the delay was decided
before the first response told it the note is shared.
- Tests: undo/conflict engine tests, lock/undo/conflict UI tests and
e2e/lock.e2e.mjs (two browsers); all three browser tests pass against a
freshly built image.

Phase 2 of the collaboration plan:
- frontend/src/lib/docSync: TypeScript port of the block tree, operations,
effects and order keys (kept identical to Go via shared test vectors),
diff from the editor's flat list to operations, IndexedDB persistence,
HTTP transport and DocSyncEngine (one request in flight, idempotent
resends, backoff, 3 s/30 s polling, keepalive flush and leave on exit,
block leases for focus, 20 s grace and new blocks).
- Text changes carry the version the user saw when typing (first change
wins when coalescing; a stale focused field keeps its old base), so a
concurrent edit becomes a conflict copy instead of a silent overwrite.
- DocumentEditor uses the engine instead of the 800 ms whole-document PUT;
editors (not only owners) can edit, remote changes appear live.
- Server: task IDs of linked blocks are delivered again, linked tasks follow
ticked/deleted blocks after sync, note tags are derived, title changes
notify other users; block IDs already used in another note are renamed
(starter content with fixed IDs was empty for every further user).
- Fix: unlinking tasks from blocks wrote to non-existent columns and never
worked (error was swallowed).
- Tests: Go/TS order key vectors, diff round trips, engine races (lost
responses, offline + reload, edits arriving between typing and sending,
stale focused field, duplicate first block), plus a Playwright test with
two browsers against the real image (e2e/run.sh).

The merge only applied to a fixed list of block types, so legacy blocks
without a type were ignored, and blocks with children were rejected.
Now only code/divider/table/progress are excluded and children move up
under the previous block. The focused bullet dot is also neutral now.

- Backspace at the start of a non-empty bullet appends its text to the
previous visible bullet (skipped for blocks with children and for
code/divider/table/progress blocks).
- Hashtags are rendered inline as clickable chips instead of a badge row
below the text, so lines no longer grow taller.
- Targeted/highlighted bullets use a neutral background instead of accent.
