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)
