fix(ir_cbm): clear PDE bit in pad config for proper pull-up input
...
PADS_BANK0 GPIO5 had PDE (pull-down enable, bit 2) still set to its
reset default. With both PUE and PDE active the pin floated to ~VDD/2,
causing the Schmitt trigger to read LOW permanently. Clear PDE in
_configure_pad() so the pull-up works correctly.
Added PADS_BANK0_PDE_SHIFT define to rp2350.h.

fix: remove duplicate docstrings from public functions in .c files
...
Public function docstrings belong exclusively in .h headers per
coding convention. Only static helper functions and static variables
retain docstrings in .c files. Removed 413 duplicate docstrings
across 185 files (15 CBM + 15 C SDK projects). All 30 projects
rebuild with zero errors.

refactor: enforce max 8 code lines, add docstrings, fix warnings across all Rust and C SDK projects
...
Rust (all 15 projects):
- Refactored overlength functions: format_counter, format_u8, format_f32_1,
format_u32_minimal, gpio_drive, read_sensor, poll_sensor, format_round_trip,
format_u32, prepare_write_buf, write_min_digits, write_temp, UartDriver::init,
init_spi, angle_to_pulse_us, compute_servo_level
- Added 200+ docstrings to test functions, mock structs, impl blocks
- Fixed pub static comments (//) to doc comments (///) in all main.rs files
- Fixed helper function ordering (helpers above callers)
- Fixed Fn(u32) -> FnMut(u32) bound in button poll_button
- Moved OneShot trait import from main.rs to board.rs in adc project
- Added unsafe {} blocks in flash unsafe fn bodies (Rust 2024 edition)
- Removed unused hal::Clock imports from pwm/servo main.rs
- All 15 projects build with zero errors and zero warnings
C Pico SDK (all 15 projects):
- Added docstrings to all public functions, macros, and static variables
- All 15 projects rebuilt with zero errors
Cleanup:
- Removed build/ and target/ directories from git tracking
- Added target/ to .gitignore
- Deleted temporary fix_rust_docs.py script

remove unused coprocessor driver from all CBM projects
...
No project uses floating-point, so coprocessor_enable() was dead code.
Removes rp2350_coprocessor.c/.h and all references from reset handlers
and Makefiles across all 15 CBM drivers (0x01-0x0f).
