feat: initial Xiao RP2040 mouse jiggler firmware

Browse Source

Embassy-based no_std firmware for the Seeed Studio Xiao RP2040 that
masquerades as a Dell MS116 USB HID Boot Mouse. Each cycle picks a
random axis from the RP2040 ROSC RANDOMBIT register, nudges +1 px,
dwells 25 ms, nudges -1 px, then sleeps 4.5 minutes. After 8 hours
elapsed from boot or RESET press the device idles silently (watchdog
still fed) until the user taps RESET (R) again, aligning a single
press with one workday.

Tooling:
- mise.toml pins rust 1.95.0 with explicit components and the
  thumbv6m-none-eabi target, plus cargo-binutils / uf2conv helpers.
- justfile shell is set to "mise exec -- sh -eu -c" so every recipe
  uses the pinned toolchain without any shell activation.
