libs: peer lib edits reach the running editor + "placed symbol updated" toast

Browse source 
synced-source subscribes to its SyncStack: remote changes (self-save echoes
consumed via a selfPushed flag) debounce per kind into kicadLibsReload — a
new embind export (pcbjam_libs_reload.h, all three TUs) that drops the lib's
plugin cache (LIBRARY_MANAGER::ReloadLibraryEntry), reloads it, and mails
MAIL_RELOAD_LIB with the nickname so the symbol tree force-refreshes (the
plugin's modify hash is a pinned constant, so a plain sync would skip it).

After the reload, kicadLibsSymbolUsage (new eeschema embind: placed
SCH_SYMBOL count across unique screens) gates LIB_ITEM_UPDATED_EVENT, and
WasmTool shows an amber toast when a PLACED symbol changed — placed copies
keep the previous version until updated from the library.

syncedScopeLibsSource gives PROJECT sessions the synced source under
VITE_LIBS_SOURCE=synced (remote contract for lib listing/createLib, lazy
per-lib SyncStacks for item ops/presync) so realtime reaches open
schematics; previously project sessions silently fell back to the per-item
remote source. Unit tests cover reload debounce, self-echo skip, per-kind
routing, usage-gated event, and the no-Module no-op.

Bumps kicad (MAIL_RELOAD_LIB force-refresh payload).
