James Dansereau b3bf7786ff M-84: fold D211 FOV refix + user-test findings into the QoL wave

D211 didn't affect the in-level view (user test): the fast3d
gfx_apply_fov_scale hook only recognised *pure* perspective matrix loads,
but GE draws the world through g_CurrentPlayer->field_10E0 -- a
projection x view matrix pre-combined on the CPU (bondview2.c:8224) --
which failed the guard. Only the pause/watch model + sky FOV changed.

Fix: scale fovy game-side at the guPerspectiveF chokepoint
(src/fr.c, #ifdef PORT, frFovY *= portFovScale, clamp 160deg), which
lands before the CPU combine. Removed the fast3d hook + gfx_api.h decl;
port/src/video.c now sets f32 portFovScale. Gated to
lvlGetCurrentStageToLoad() != LEVELID_TITLE so the front end (which
renders through the same path) keeps its authored FOV.

User-verified: menu unaffected, in-level view widens (Dam tunnel).
Caveat: currentPlayerSetCameraScale keeps nominal FOV for frustum-cull
/ screen<->world math (edge geometry culls slightly early at high scale).

Adds src/fr.c as a #ifdef PORT game-code touch (D181 policy class).

Docs (this test pass):
- D214: config.c sections by the last dot, so binds live in [Input.Bind]
  not [Bind]. Doc-only fix (finding, index, QOL-INVENTORY); code unchanged.
- D217 (OPEN): viewmodel + 3rd-person Bond model textures render garbled
  -- stale-palette CI-texture bug (D161 family), surfaced by D215.
- D218 (LOGGED, parked): wide FOV exposes the per-level FarFog
  draw-distance boundary; Video.DrawDistance fix proposed.

GoldenEye 007 — PC port layer

This directory contains the PC port layer: the code that lets the (unmodified) GoldenEye game sources run on a modern host instead of N64 hardware.

It mirrors the layout of the Perfect Dark PC port, which ports the same Rare engine family. See docs/internals.md (repo root) for the full research write-up and phased plan.

How it works (short version)

The R4300 game code (src/game, src) is compiled unmodified.
The RSP is emulated in software (fast3d/): it interprets the Gfx display list the game builds and emits OpenGL calls, bypassing the RDP.
The RCP scheduler (gesched.c) replaces src/sched.c's hardware task submission: instead of writing RSP registers it calls gfx_run().
libultra OS functions are shimmed in libultra.c (single-threaded, host clock, VI/PI/SI/AI mapped onto the video/audio/fs/input layers).
Saves (Memory Pak / EEPROM) are backed by files in the data dir.

GE-specific RSP work

The PD fast3d already handles G_TRI4 (GE's 4-triangle command). The new work for GE is:

G_SETTEX — GE's custom texture-bank command (include/gbi_extension.h, gsSPUseTexture). Must be added to the RSP interpreter + GL backend.
Verify GE's custom color-combiner modes (G_CC_*FADE*) and render mode (G_RM_CUSTOM_AA_ZB_XLU_SURF) produce correct GLSL / GL state.

Use rsp/graphics/gmain.s (the real GE RSP ucode) as the ground truth for the exact command encodings.

Status

Scaffolding only. The files in src/ and fast3d/ are stubs that define the interfaces and mark the work to be done. The actual implementation is brought in phase by phase (see docs/internals.md §8), largely by adapting the PD port's port/ layer.
