sl-controls 64de6667b6 feat: PID gain scheduling for speed-dependent balance (Issue #550) ...

Implements a speed-dependent PID gain scheduler that interpolates Kp/Ki/Kd
across a configurable table of velocity breakpoints, replacing the fixed
single-gain PID used previously.

Changes:
- include/pid_flash.h: add pid_sched_entry_t (16-byte entry), pid_sched_flash_t
  (128-byte record at 0x0807FF40), pid_flash_load_schedule(), pid_flash_save_all()
  (atomic single-sector erase for both schedule and single-PID records)
- src/pid_flash.c: implement load_schedule and save_all; single erase covers
  both records at 0x0807FF40 (schedule) and 0x0807FFC0 (single PID)
- include/pid_schedule.h: API header -- init, get_gains, apply, set/get table,
  flash_save, active_band_idx, get_default_table
- src/pid_schedule.c: linear interpolation between sorted speed-band entries;
  integrator reset on band transition; default 3-band table (0/0.3/0.8 m/s)
- include/jlink.h: add SCHED_GET (0x0C), SCHED_SET (0x0D), SCHED_SAVE (0x0E)
  commands; TLM_SCHED (0x85); jlink_tlm_sched_t; JLinkSchedSetBuf;
  sched_get_req, sched_save_req fields in JLinkState; include pid_flash.h
- src/jlink.c: dispatch SCHED_GET/SET/SAVE; implement jlink_send_sched_telemetry,
  jlink_get_sched_set; add JLinkSchedSetBuf static buffer
- test/test_pid_schedule.c: 48 unit tests -- all passing (gcc host build)

Flash layout (sector 7):
  0x0807FF40  pid_sched_flash_t (128 bytes) -- schedule
  0x0807FFC0  pid_flash_t       ( 64 bytes) -- single PID (existing)
