OpenSNES v0.37.0

What's in this release

The DSP-1 v2 release: the coprocessor module gains the canonical 3D
pipeline — true hardware perspective — plus the game-logic commands, and
the dsp1_cube example renders with a real perspective divide computed
on the NEC µPD77C25.

Added

• feat(lib): DSP-1 pipeline completed — dsp1Project (world → screen
  H/V + depth scale M), dsp1Parameter (projection-plane setup, 7 in /
  4 out), dsp1Distance (hardware sqrt of a 3D vector), dsp1Range
  (sphere test for collision/LOD), dsp1Present (bounded known-answer
  probe that never hangs on a missing chip), and fixed↔T/A bridge
  macros between the SDK's 8.8 fixed-point and the DSP-1's 1.15/angle
  formats. Projection semantics characterised empirically on luna
  (DSP-1B) and recorded: the all-zero Parameter setup is degenerate,
  azs=$4000 makes +Y the view axis, effective focal length ≈ lfe+les.
• docs(docs): new DSP-1 tutorial (docs/tutorials/dsp1.md) — chip
  model, RQM handshake, slot types, the Attitude→Objective→Project
  pipeline, Distance/Range for game logic, firmware gotchas; DSP-1 rows
  in API_INDEX.md; snes.h opt-in list now mentions dsp1.h and
  panel.h.
• ci: the native luna test-manifests pillar now runs in CI (it
  previously ran only locally via make tests); the DSP-1 manifest
  additionally asserts the full DR/SR handshake path (dsp1_ok = 1),
  firmware-gated so it SKIPs cleanly on firmware-less runners.

Changed

• feat(examples): chips/dsp1_cube upgraded from orthographic to
  hardware perspective projection; chips/README.md gains the 11.5
  rung and now presents the three-chip family.
• build: USE_DSP1 := 1 auto-adds the dsp1 module to LIB_MODULES
  (aligned with the SuperFX/SRAM pattern).

Fixed

• docs(examples): the dsp1_cube README documented a luna run --dsp1-rom
  flag that does not exist in the pinned luna — corrected to the
  luna state --dsp1-rom install path; the stale Python-probes section
  of the luna-test README replaced with the manifests view; dsp1_cube
  baseline provenance repaired (visual and WRAM baselines were captured
  from different builds).
