* feat(scene-graph): let a SceneGraph take its ID generator
The constructor accepts an ID generator, used for the root node and for
nodes, variables, and collections created later; generated IDs skip any
node, variable, collection, or mode ID already in the graph.

* perf(scene-graph): check mode IDs without allocating per created entity
Generating an ID spread every collection into a new array and scanned it
for each candidate, which runs on every createNode. Check the node,
variable, and collection maps first and walk the modes with an early exit.
An index of mode IDs is not kept because history snapshots, transfer, and
undo replace collection maps and edit modes in place, which would leave it
stale.
* test(scene-graph): cover injected ID generators and collision skipping
* docs: note the SceneGraph ID generator in the changelog
* test(core): keep reopened .fig GUIDs when a sibling is inserted before them
Refs #770
* test(collab): cover concurrent additions, same-property writes, and delete versus edit
Move the synced-store harness to tests/helpers/collab so the new cases
live in tests/app/collab, and let it bind graph events as a collab session
does. The cases edit both peers while disconnected and check the
converged graphs.
Refs #770
* fix(scene-graph): keep a collection's IDs apart and stop on an exhausted generator
createCollection asks for the collection and default mode IDs before
registering either, so a generator repeating a candidate gave both the
same ID. A generator that only returned taken IDs looped forever, even in
the constructor; it now throws after a bounded number of attempts.
* test: require the inserted GUID and a real disconnect in new tests
The GUID test passed even if export dropped the inserted layer, and the
concurrent-edit helper would have tested sequential sync had its peers
not been disconnectable.
* feat(scene-graph): create variable modes through the graph's ID generator
The editor minted added and duplicated modes as mode:<random hex>, so an
injected generator governed every graph entity except modes added after
a collection's first. SceneGraph.createMode mints the ID and adds the
mode; undo and redo replay it with addMode.
* test(core): type the reopened .fig buffer in the GUID test
* refactor(scene-graph)!: share random helpers and one component property ID
randomHex, randomInt, and randomIndex move from @open-pencil/core/random
to @open-pencil/scene-graph/random, so format packages can use them:
design-jsx and the MCP test server dropped private copies. Component
property IDs, written as prop:<random hex> in six places across Core and
design-jsx, come from createComponentPropertyId.
* docs: point the randomness rule at the shared ID and random helpers

* feat(canvas): draw agents' cursors as outlined sparkles
Editor state's remoteCursors becomes presenceCursors with a kind, since the list now includes local agents. People keep the filled arrow; an agent is a sparkle outlined in its owner's color, with an outlined name pill, so whose agent it is reads from the outline. Cursor drawing moves out of the pen overlay into canvas/overlays/presence.ts.
* feat(app): publish AI agent presence to collaborators
The built-in chat now appears as an agent with a callsign while it replies, at the nodes its tools touch on the run's page, and goes idle (off the canvas) when the reply ends. Agents live in a per-document presence registry and are published in their owner's awareness state, so collaborators see each other's agents in the owner's color; the payload is metadata only.
Peer awareness was cast without checks. It is now validated with Valibot, invalid fields are dropped rather than the peer, and names, selections, and agent counts are bounded.
* feat(app): follow agents and list them in the share panel
Following lived in collab and only knew people. It moves into the presence registry with a person-or-agent target, so you can follow anyone's agent, including your own outside a room: the view goes to the agent's page and keeps its cursor centered, stays attached while it idles between replies, and lets go when it leaves. A new editor action, centerOn, replaces reading the canvas size from the DOM. Peer cursors keep their zoom so following a person still matches it.
The share panel lists everyone in the room with their agents, each with its status, page, and a follow toggle, and your own agents can be renamed inline. CollabPanel moves to collab-panel, and the two-browser relay helpers move out of the collab spec into tests/helpers/collab.
* docs(collaboration): list the agent model among shared presence
* test(vue): a canvas story for presence cursors
Storybook now serves CanvasKit, so a story can render the real canvas:
people's arrows and agents' outlined sparkles, with controls for names,
colors, and zoom.
* feat(canvas): mark agents with a sparkle label instead of a sparkle cursor
A sparkle on its own did not read as a pointer. Agents now point with
the same filled arrow as people, in their owner's color, and their
outlined label starts with a sparkle.
* refactor(app): split the collaboration theme by component
One 18-slot theme served five components that each used a few slots,
with variants that applied to one slot. Avatars, the share button, the
presence list, page markers, and the mobile presence popover now have
their own themes, exported as tv() like the rest of src/theme.
* fix(app): truncate an agent's status before its name in the presence list
In a narrow share panel the status kept its width and the callsign
shrank to its first letter.
* feat(app): show presence and following on the toolbar avatars
The share popover held who was online, the Share button turned into a
Connected status, and following gave no feedback. Collaborators' avatars
now count their agents and list them on hover, your avatar holds your
agents and Leave room, and +N collects the rest. A frame and bar in the
followed color show whom you follow; your own input or Escape stops it.
The share popover keeps the room link, and Share keeps its label.
* fix(app): address review of following from the avatars
Escape stops following from the follow frame, once and not while typing
or after another control handled it. The frame shows the agent sparkle
as an icon. A test pins that following survives the target changing
pages mid-switch, and the test relay tolerates frames that are not JSON.
* fix(app): follow until you leave, wait for silent peers, reach agents by keyboard
Following records the page it put you on, so any other page change ends
it, even of a resting agent that would otherwise pull you back later. A
present peer without a cursor yet is waited for instead of dropped. The
room list button is always there, so keyboard users reach agents that
hover cards only show to the mouse. centerOn ignores points too far away
to represent, and the docs describe following from the avatars.
* fix(app): stop following on any zoom of yours, and keep follow switches from restarting
Keyboard and menu zoom changed the view without the pointer or wheel
input the frame listens for, so following kept going and later undid the
zoom; any viewport change following did not make now ends it. Cursor
updates no longer restart a switch already heading to the same page,
which could keep a slow page from committing. The room's connected
store is reactive, and agent rename starts on a single click.
* fix(app): never loop on a followed cursor's unknown page, and stop on zoom mid-switch
A peer's cursor could name a page this document lacks; following then
retried a switch that never moved, forever. Following now waits on such
cursors and only re-syncs after a switch that landed. A page switch
restores its viewport without viewport:changed, so your zoom during a
follow switch now stops following too.
* fix(app): cancel a loading follow switch when following stops
Stopping following, by Escape, your own input, or zoom, left a follow
page switch loading, which then took you to their page anyway. Stopping
now overtakes it with a switch to the page you are on.
