Rewrite mt1959.rs: complete platform driver with full profile support
...
Complete rewrite of MT1959 platform driver:
- All 10 handlers implemented matching firmware logic 1:1
- load_firmware(): WRITE_BUFFER ld_microcode on cold boot
- calibrate(): full zone probe + speed table + triple SET_CD_SPEED
- init(): x86 dispatch sequence (unlock → fw × 6, calibrate × 6)
- read_register_a/b(): use pre-built CDBs from profile
- set_read_speed(): speed table lookup per zone
- status(), probe(), keepalive(), timing()
Platform trait updated:
- Renamed read_config → load_firmware (matches actual function)
- Added init() for full x86 dispatch sequence
- Renamed read_sectors → set_read_speed (operation sets speed, not reads)
- Split read_register into read_register_a/b (separate CDBs)
Profile fields used:
- drive_signature, unlock_init_value, unlock_response_size_minus_init
- ld_microcode (1888B firmware payload)
- hardware_register_a_cdb, hardware_register_b_cdb (pre-built CDBs)
- drive_nominal_speed_cdb (calibration triple-play)
- speed_zone_table, speed_calc_table (operation lookups)

Strip to bare minimum for speed test: no calibration, no maintain_speed
...
Back to basics: open, unlock, SET CD SPEED max, read.
Remove all calibration probes, register reads, maintain_speed calls.
This is closest to the build that hit 17 MB/s earlier.
Also: drive discovery moved to libfreemkv (find_drive, resolve_device),
AACS via UDF only, clean pipeline, sg device support.

Refactor: Chipset architecture, remove supported/status gatekeeping
...
- PlatformType → Chipset enum (MediaTek, Renesas)
- unlock_mode + unlock_buf_id stored in profile, not derived from enum
- Removed ReadinessStatus, supported field, needs_flash — library is agnostic
- Removed DriveMatch/Flashable — if we have a profile, try unlock
- profiles.json: chipset + unlock_mode + unlock_buf_id, no program/supported
- mt1959.rs reads mode/buf_id from profile fields directly
- Tests: find_known_drive, find_unknown_drive

Structured error codes: E1000-E5000, no user-facing text in library
...
Error codes:
1000-1001: device errors (not found, permission)
2000-2002: profile errors (unsupported, not found, parse)
3000-3003: unlock errors (failed, signature, not unlocked, not calibrated)
4000-4001: SCSI errors (command failed, timeout)
5000: I/O errors
All errors carry structured data (vendor_id, opcode, etc).
Applications format their own user-facing messages.
Library returns code + data, never English text.
