mr.one f4b344cccd Implement NUFLI delta encoding with scanlines
- Add tools/apply_scanlines.py for CRT scanline effect
- Add tools/nufli_delta.py for delta encoding (base + bitmask deltas)
- Delta format: 2880 byte bitmask + N byte values per screen
- 40.1% size reduction vs raw NUFLI (69KB vs 115KB for 5 screens)
- Base (23KB) at 000-FFF, title delta (7KB) at -
- Other deltas use title as fallback (TODO: disk loading)
- Update tasks.md with scanline and delta encoding documentation

ballz 64b0790519 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)

ballz b7219dccfc Replace src/build.sh with Makefile (GNU make)
New targets:
  help (default)     — show usage (was the -help/--help equivalent)
  compile            — compile main.c → build/nyuller.prg
  run                — compile + run in oscar64 built-in emulator
  run-vice           — compile + run in VICE x64 (foreground)
  run-vice-cycle     — compile + run in VICE x64sc (cycle-exact)
  play               — compile + launch VICE x64 detached
  play-cycle         — compile + launch VICE x64sc detached
  kill               — kill any detached VICE
  clean              — remove build/ artifacts
  build/nyuller.d64  — build the .d64 disk image from the .prg

Optimization: override with 'make OPT=O3' (or O0/O1/O2/Os/g).
Default is -O1 (oscar64 default).

The Makefile builds oscar64 automatically if missing, uses
c1541 to create the .d64 with verification, and passes
-drive8type 1541 to VICE (required for autostart).

Removed src/build.sh and updated all docs (README, tasks.md,
AGENT_CONTEXT.md, GAME.md, helloworld.c) to reference make.
