Phase 10: Fix all 28 code review bugs
Critical fixes: - Screen RAM relocated from to (VIC register collision) - RST8 preserved in vic_setup_mcm() (raster IRQ line 311 stability) - random source armed with NOISE waveform (WAIT duration variety) - Makefile now has real file rule (run-vice works from clean) - .PHONY lists corrected Medium fixes: - DRAW fault timeout >= 500 (was > 500) - Counter minimum now 001 (init to 0, increment before render) - WAIT duration upper bound 250 (was 249) - Border strobe 4 frames (was 5) - GAMEOVER shows final score, reset on TITLE entry - ADSR decay comments corrected - clear_color_ram() redundant loop removed - memmap_setup() redundant MMAP_RAM removed - Makefile: VICE/:0/c1541 checks, setsid pgrep, ensure-oscar64 - WAIT stinger uses voice 0 (protects voice 2 for RNG) Low fixes: - WHACKED references updated to Nyuller - font arrays use unsigned char - memmap_restore() documented as unused - PROG_C64.md banking table corrected - Makefile: clean @ prefix, help docs, OPT guard - Audio schedule off-by-one corrected (+1 frame/note)
