libs 0017: sync overrides indexed + stale-lib session menu + Cmd+S DOM-focus fix + WasmTool split
- kicadLibsFootprintUsage + kicadUpdateFromLibrary embinds (result via
  pcbjam:lib-update-done — runOnCoroutine is deferred)
- standalone: stale-lib FAB triangle + session-menu Update-from-library row,
  save busy notice names the item, footprint placed-usage in the toast
- WasmTool.tsx split: module helpers → components/wasm-tool/
- specs: save-cmd-key (Meta+S, mac UA), fpedit-cmd-save (DOM-focus repro)
- wxwidgets → cdd5a5c (wxDomBlurActive)

// bare item tokens like `(segment`/`(via`/`(zone` are NOT accepted by the parser top-level, so
// the envelope is required).
//
// The envelope still comes from CLIPBOARD_IO::SaveSelection, which is also what supplies the
// `(layers …)` block the parser needs; CLIPBOARD_IO normally talks to the system clipboard, so
// SetWriter/SetReader redirect it to a string to work headless / in wasm. Footprints take the
// dedicated path below instead — see blobForItem for why the clipboard dialect is wrong here.
// A board writer we can point at a BOARD. PCB_IO_KICAD_SEXPR's default control set is
// CTL_FOR_BOARD — exactly what a .kicad_pcb save uses — but only CLIPBOARD_IO exposes a
// public SetBoard(); m_board is protected on PCB_IO, so a two-line subclass gets us the

//
// The blob MUST be byte-equal to that item's subtree in a full .kicad_pcb save: the Y.Doc is
// the source of truth for the FILE, so any writer difference is a permanent, unfixable drift
// and corrupts what a server-side materialize writes.
//
// That is why footprints use CTL_FOR_BOARD and not CLIPBOARD_IO's CTL_FOR_CLIPBOARD. The two
// differ by exactly CTL_OMIT_FOOTPRINT_VERSION (pcb_io_kicad_sexpr.h), so clipboard form emits
// (footprint "Lib:C1206" (version 20260206) (generator "pcbnew") (generator_version "10.0") …)
// — three tokens a board-embedded footprint never has (pcb_io_kicad_sexpr.cpp ~1201). Every
// footprint of every board drifted on those three lines.
//
// Non-footprints DON'T use SaveSelection either (drift-trio finding, standalone-hardening
// 0008 §10): its "make safe to transfer" step clears the locked flag on the copy
// (kicad_clipboard.cpp ~416) — clipboard semantics; pastes are unlocked — so `(locked yes)`,
// real file content, vanished from every track/via/zone/text blob and a peer's lock never
// reached the doc. Instead the live item is Formatted directly with the FILE writer and
// wrapped in the same synthetic `(kicad_pcb … <layers> <item>)` envelope the apply path
// already parses (the parser rejects bare `(segment`/`(via`/`(zone` at top level).
//
// Footprints also DON'T go through SaveSelection: its "make safe to transfer" step copies the
// footprint, and FOOTPRINT's copy ctor ASSIGNS the mandatory fields into the new footprint's
// freshly-constructed ones (`*existingField = *field`; EDA_ITEM::operator= keeps the target's
// uuid) — so Reference/Value/Datasheet/Description would carry NEW uuids in every blob,
// breaking the wire's identity-by-uuid (every emit would read as field remove+add, and round
// trips lose the field uuids). The copy ctor now restores those uuids itself (footprint.cpp),
