fix(drift-trio): phase E — serialized fiber queue (#10a) + fiber-busy probes
runOnFiber now runs bodies strictly one-at-a-time through a park-safe FIFO
(collab_common.h): the per-body fire-and-forget coroutine interleaved under
load — an asyncify park inside commit.Push let the event loop start the next
body, so a local commit and a remote apply ran interleaved on shared state
(s_applyingRemote is one global), silently losing applies on the actively-
editing receiver (fuzz finding #10a; B now fuzzes clean; 39-test suite green).

kicadCollabFiberBusy embind probe (merged + standalone registrations): a
bare-embind-stack scratch save during a parked fiber mis-dispatches (table
index OOB) — trio.ts modelText/drift and production drift-detect now defer
while fiber work is in flight (#10b hardening; the trap's root cause is still
open and needs a symbolized stack — fuzz stays fixme'd).

// eeschema port of pcbnew's presence layer (0002 — see pcbnew_embind.cpp for the full
// design rationale). The state + event/scheduling machinery live in the shared
// pcbjam_presence::CORE (collab_presence_core.h); this TU supplies only the
// eeschema-specific hooks: frame/tool lookup, KIID resolution via
// SCHEMATIC::ResolveItem, the bare-uuid selection payload, and the per-peer draw
// (cross-app ghosts gated to the CURRENT sheet). Zero kicad-fork changes: wx-layer
// Bind() triggers on the GAL canvas + the COLLAB_LISTENER piggyback, selection read
// post-settle from SCH_SELECTION_TOOL. Rooms are per-sheet (warm pool), so peers
// publishing cursor/selection in the bound room are BY CONSTRUCTION on this same
// sheet file — no sheet filtering is needed for same-room selections; the JS side
// rebinds the whole presence layer on sheet navigation (onSheetChanged) and clears
// the overlay in between.
// Cross-app selection (0006): the schematic items a peer's xsel (symbol uuids
// from a pcbnew peer) resolves to on the CURRENT sheet. Unlike same-room
// selections (per-sheet rooms scope those by construction) xsel arrives
// project-wide, so only items that resolve onto the sheet THIS canvas is
// showing count — a bbox from another sheet's screen would land at meaningless
// coordinates. ONE resolver shared by the ghost render and the test probe
// (kicadCollabTestGetCrossMapped), so the assertion can't drift from the pixels.
