Adds the per-track end-action model designed in docs/track-format.md §3, end to
end across both engines, both firmwares, and the editors.
Grammar (parsed + serialized by engine.js and both app.py):
rep=<n> cycles before the end-action fires (default 1)
end=stop stop after rep cycles
end=next advance one track (sugar for end=+1)
end=<±N> relative goto after rep cycles (e.g. end=-2 = D.S.)
(absent) loop forever — the metronome default
Firmware runtime (pico-cp + pico-explorer): _on_new_bar now consults a per-track
_end_plan() and fires stop / gapless-advance / relative-goto at the right bar.
A cycle = b<bars>, else one master bar; fire bar = rep * cycle. Explicit end=
governs; with no end, the global Continue toggle stays a default (=end=next, still
needs b<bars>) so existing set-lists and the CONT UI are unchanged. _prepare_next
takes a target index; the seam machinery, _do_advance and live-sync all carry rep/end.
Editors (editor.html + editor-beta.html): state.rep/state.end thread through
applySetup / currentSetup / currentPatch so load -> edit -> save preserves the
flow; authoring is via the program-string field (no graphical control yet).
Tests: the 3 playback-flow vectors now pass on both engines (39 pass / 3 known).
Runtime decision logic (_end_plan / _goto_target) unit-tested for stop, rep,
relative goto clamp/wrap, and legacy-Continue precedence. Codec round-trip
verified idempotent. Both firmwares compile + mpy-cross clean.
Also: untrack stale __pycache__/*.pyc build artifacts and gitignore them.

From on-board feedback (works well; minor tweaks):
- Pad grid uses circles now: big circle on each beat (division), small on the
subdivisions (vectorio.Circle — native, no extra cost), coloured/lit as before.
- Lane labels use a new small font (font_s.bin, ~12px via gen_font.py) so they're
half-size and show more of the voice name (e.g. 'hatClos').
- LED was blinding -> LED_BRIGHTNESS scale (default 0.15) applied on every write.
- Residual tearing -> SPI back to 62.5 MHz (vendor speed; smaller tear window on a
panel with no tearing-effect pin). Both are CONFIG flags.
Verified by rendering the full scene headless. font_s.bin added to gen_font.py + bundle.

Four firmware improvements (web simulator already had these):
- Smooth lettering: replace the upscaled 8x8 bitmap font (and the 7-seg BPM) with
baked anti-aliased proportional fonts (DejaVuSans-Bold 22 + 78), rendered by
blending fg over bg through a 16-entry alpha LUT. Generator: pico/gen_font.py.
- All grooves: PROGRAMS now carries the full web set list (23 grooves), not 5.
- Fix: the RGB LED stayed lit when stopped — the stop path now zeroes the colour
and the fade only runs while playing (led_off()).
- Fix: the on-screen play button played one beep then stopped — a finger held past
the old lockout re-fired the toggle. Touch is now edge-detected like the hardware
buttons (fires once on finger-down, ignores held).

A user dropped main.py onto the RPI-RP2 BOOTSEL drive (which only accepts a .uf2)
and it vanished on reboot. Clarify in pico/README.md and info-kit.html that
flashing is two distinct steps: (1) drag-and-drop the MicroPython .uf2, then
(2) copy main.py over USB serial with Thonny/mpremote — the Pico is not a USB
drive once MicroPython is running.

The on-screen header showed VARASYS + the model; since the wordmark is already
silkscreened on the case/PCB, keep only the PM_K-1 KIT label on the display.
Applied to both pico/main.py (draw_static) and the kit.html web simulator.

A new, first-actually-buildable form factor for the 52Pi EP-0172 "Pico Breadboard
Kit Plus" (Raspberry Pi Pico; 3.5" ST7796 320x480 cap-touch via GT911, PSP
joystick on ADC0/1, WS2812 RGB on GP12, buzzer GP13, buttons GP14/15):
- pico/main.py — one self-contained MicroPython file: ST7796 direct-draw driver,
GT911 touch (16-bit register addressing), WS2812 RGB (neopixel), PWM buzzer,
ADC joystick, buttons. It parses the project's own program-string language
(verified against the web engine's semantics) and runs a non-blocking
ticks_us scheduler with an on-screen touch UI. CONFIG flags cover panel /
colour / touch / joystick calibration. pico/README.md has flashing +
calibration steps.
- kit.html — lean widget that mirrors the firmware's on-screen UI (portrait
320x480 canvas) plus a joystick / RGB / buzzer / A-B buttons; plays via the
shared engine. info-kit.html — the real EP-0172 pinout, a parts list
(~$45 incl. Pico) and the firmware to flash (downloads /pico-main.py, links
the README + source).
- Landing + embed page list the Kit; build.sh/deploy.sh build the two pages and
serve pico/main.py as /pico-main.py for download.
