fix(codes): bound every 2D encoding step under the watchdog; draw large codes from runs

M6's step sizes were estimates, only exercised with small codes. With the largest inputs the app accepts, every 2D encoder tripped the watchdog on the Forerunner 255S (and the biggest steps were far over the 768 KB watches' limit), so a large code added from the phone would have stopped the app during settings processing at every start. - QR: resumable segmentation, Reed-Solomon, interleaving, function patterns and final mask; mask scoring on rows and columns packed 16 modules per word (same penalties, checked against the per-module rules). - Reed-Solomon: resumable field tables and generator, encoder shifting with native slice. - Data Matrix, Aztec, PDF417: resumable encodation, stuffing, compaction, placement and build; Data Matrix's grid as a byte array (90 KB -> 35 KB); PDF417 refuses text that can't fit the screen before compacting. - Cache format 2 with 16-bit sizes (wide PDF417 was cached wrong); packing in steps; codes drawn as runs, and from a bitmap painted in steps when a frame can't draw all runs. - The job runner does two steps per tick on 768 KB watches; gen_products --check verifies each product's watchdogCount fits that. - CodeView renews full brightness (AMOLED) or the backlight (MIP) for up to a minute from its single ticker; a tap restarts the minute.

- sim_screenshot.py finds the device drawing in the simulator window, crops the screen and compares it with approved golden images. - check_budgets.py reads key=value DIAG/HARNESS lines (the simulator console escapes quotes, so JSON was dropped). - ciq_test_report.py accepts SDK 9.2.0's real summary line `PASSED (passed=N, failed=N, errors=N)`; a captured log is a fixture. - gen_products.py checks all manifest products are watches with API 5.0+ and at least 512 KB for apps. - lint_project.py rule HDR001: every file carries the Author/Summary header (JSON keys, PNG text chunks; generated package-lock exempt). - make_icon.py --all draws one icon per launcher size in use. - Golden screenshots for fr255s, venusq2, fr70 and fr965. - 44 tests, warnings as errors, ruff and mypy --strict clean.
