Release v0.1.1-beta2

What's New

Fixed: PY32F071 (V3/K1) CPU detection

The detect_cpu() heuristic now uses the Reset vector address (offset 0x04
in the ARM vector table) instead of SysTick. PY32F071 bootloader sits at flash
start (0x08000000–0x080027FF), so the firmware Reset vector is always ≥
0x08002800. Rule: Reset >= 0x08002000 → Py32f071. Works on all tested
images — stock, custom, live-flashed.

Fixed: strict per-CPU flash size limits

The auto-extension logic that allowed oversized images (up to 0x14000 / 80KB) has
been removed. Per-CPU limits are now strictly enforced to protect the bootloader:

CPU	Revision	Flash limit	Bootloader location
DP32G030	V1	0xF000 (60KB)	End of flash (from 0xF000)
PY32F030	V2	0x10000 (64KB)	End of flash
PY32F071	V3/K1	0x12000 (72KB)	Start of flash (0x0000–0x27FF)

Images exceeding the limit are rejected with FirmwareError::TooLarge.

--force-cpu flag

The flash subcommand now accepts --force-cpu <CPU> (dp32g030 / py32f030 /
py32f071). Now optional for normal use (auto-detection is correct), still
available for non-standard builds. Works in both --dry-run and live mode.

Cross-platform Python test scripts (test-scripts/)

Three self-contained scripts (Python 3.12+, stdlib only). Auto-discover the
rustsheng binary. Tee-logging to report.txt, byte-level diff for write tests.

Hardware validation

All scripts tested on real hardware — Windows 10, COM4.

Revision	Read	Write	Flash
V1 (DP32G030, fw 2.01.39, bl 2.00.06)	OK	OK	OK (2.01.26)
V3 (PY32F071, fw 7.00.11, bl 7.00.07)	OK	OK	OK (auto-detected)
