JakubandClaude Sonnet 5 b2cf459460 fix(sim): text-width/render bugs, splash version, wasm-fetch error, battery lag 
Code-review pass over the buzzer/sim commits turned up several real bugs,
plus two issues found afterward from manual browser testing:

Rendering (SimDisplayDriverCanvas, variants/sim/SimDisplayDriver.h + target.cpp):
- getTextWidth() measured UTF-8 BYTES (strlen()*6), not codepoints. Since
  b067e95b stopped stripping accents, any accented string now measures
  double its real width -- mis-centred titles, premature ellipsis/marquee,
  badges pushed off-screen. Now uses the real MiscFixedRenderer measurement
  (miscFixedTextWidth()), same as SH1106Display/SSD1306Display.
- Added the matching getCodepointWidth() override (O(1) single-glyph
  advance), same pattern as SSD1306Display.
- isSingleFont() was left at the base class's `false`, though this backend
  only ever renders MiscFixed -- UITask.cpp's status-bar indicator height
  keys off this (`lh-2` vs `lh`), so the sim drew it 2px taller than a real
  board.
- print() blitted the full 128x64 canvas on every call (dozens per frame,
  60fps) -- now tracks a dirty bounding box and only clears/blits the
  region actually touched.

Web Audio (buzzer bridge, index.html + mesh.html):
- No AudioContext.resume() -- a context created (or later suspended) in the
  'suspended' state (Safari/Firefox, or any browser backgrounding the tab)
  stayed silent forever. Now resumed on every gesture.
- linearRampToValueAtTime with no anchoring setValueAtTime interpolates
  from the LAST scheduled event, not "now" -- so the anti-click ramps could
  effectively snap instead of fading. Fixed with cancelScheduledValues +
  setValueAtTime(current) before each ramp.
- mesh.html: a gesture only armed the clicked instance's audio. Click A,
  send A->B, and B (the one actually meant to beep on receipt) stayed
  silent. Now any gesture arms both A and B.
- RTTTL rests (freq=0, still "playing") now explicitly hold pitch and drop
  gain instead of it happening to work by coincidence.

Misc: sim_test_get_num_contacts() was missing the g_sim_ready gate every
other sim_test_* hook has, so it could return a bogus negative count before
setup() finishes seeding num_contacts.

Splash screen missing "Solo <version>" bar: variants/sim never defined
FIRMWARE_SOLO_BUILD (every real Solo board does), so SplashScreen silently
skipped that whole line -- the sim looked like a plain non-Solo companion
build. Added -D FIRMWARE_SOLO_BUILD=1 to platformio.ini and build_wasm.sh.
Verified on a real canvas screenshot: "MESHCORE 1.17.1 / 19 Aug 2026 /
Solo v1.27".

Wasm-fetch error message: "failed to start: RuntimeError: Aborted(both
async and sync fetching of the wasm failed)" is Emscripten's own opaque
message for the single most common real cause -- the page opened via
file://...index.html instead of served over http(s) (fetch() on a local
file is blocked by CORS in both Chrome and Safari, confirmed by reproducing
the exact same error/stack via file://). Both harnesses now detect
location.protocol === 'file:' and show an actionable message with the
one-line fix instead of the raw stack trace.

Battery-set latency: SimMainBoard's battery value is an exact, instantaneous
JS-set integer (see sim_battery_set_mv()), but UITask's battery-check code
polls it every 8s and runs it through an EMA (alpha=0.2) meant to smooth a
REAL board's noisy ADC -- so a value typed into the demo UI could take tens
of seconds to visibly settle. SIM_PLATFORM now checks every 250ms and skips
the EMA (nothing to smooth), since the reading is already clean. Measured
on real canvas pixels: indicator update now lands within one screen-refresh
cycle instead of up to 8s+.

; variants/sim -- native (host) build of the real companion_radio app logic
; (MyMesh/UITask/DataStore), for Phase 1 of the in-house browser-sim project
; (see the plan doc / project memory for the full Emscripten roadmap this is
; step one of). No Emscripten here yet -- plain g++, a terminal ASCII-art
; "display", stdin for input. Deliberately the easiest possible target so the
; from-scratch port can be debugged without WASM complexity on top.
;
; Not `extends`-ing arduino_base/esp32_base etc: those pull in RadioLib, Wire,
; SPI and a real Arduino framework, none of which this build wants -- it's
; written against platform=native from scratch, closer in spirit to
; [env:native]/[env:native_kiss_modem] below than to a real board env.

; Phase 3: native build of the real examples/simple_repeater app logic
; (MyMesh/no UI) against the same variants/sim/ interfaces as
; [env:sim_companion_radio] above. No DISPLAY_CLASS defined -- a repeater
; doesn't need one (examples/simple_repeater/main.cpp already gates its
; UITask/display use behind #ifdef DISPLAY_CLASS, same as every real
; headless-repeater hardware env does), which also means UITask.cpp/.h
; never need to be ported/compiled for this target at all.
;
; Everything else mirrors [env:sim_companion_radio] deliberately closely
; (same src/*.cpp list, same real hardware envs' own convention of sharing
; one broad src/helpers/*.cpp filter across companion_radio/simple_repeater/
; room_server -- see e.g. variants/ebyte_eora_s3/platformio.ini's
; [env:Ebyte_EoRa-S3] base + its "_Repeater" env only adding
; "+<../examples/simple_repeater>" on top) -- a few of those .cpp files
; (BaseChatMesh.cpp, ConfigSerializer.cpp, DeviceDiag.cpp) aren't actually
; reachable from simple_repeater's own code, but compiling them in unused is
; harmless and keeps this env a straightforward diff against the one above
; rather than a hand-pruned, easy-to-drift-out-of-sync list.
