_resolveFreeCam() (keys/drum) and _freeCamFor() (highway_3d) guarded the panel
map lookup with only `i != null`, so a non-integer / negative / string index
from panelIndexFor() could resolve an unintended or inherited property (e.g.
map['toString']) instead of cleanly falling back to the global camera. Gate the
index on `Number.isInteger(i) && i >= 0` before `map[i]`, matching the hardening
already applied in _bgPanelKey(). Extend the resolver tests with float/string
(prototype-key) cases. Behavior change only for malformed indices.

- _bgPanelKey() treated any non-null panelIndexFor() return as a valid panel id,
so a NaN/non-finite index minted a bogus "panelNaN" localStorage key instead
of falling back to "main". Gate on Number.isInteger(idx) && idx >= 0. (The
camera path is already NaN-safe — panelsMap[NaN] misses and falls through.)
- Add a NaN/negative-index case to the resolver tests (drum 22, keys 57, pass).
- Convert the camera-bridge helpers' comments to JSDoc (_bgPanelKey, _freeCamFor,
_resolveFreeCam, _ssApi across the three plugins) to lift docstring coverage on
the changed surface. Comment/robustness only; no behavior change beyond the
NaN guard.

Three review findings on the per-panel camera work:
- highway_3d: _bgPanelKey() resolved splitscreen via window.feedBackSplitscreen
only, while _freeCamFor() uses the feedBackSplitscreen||slopsmithSplitscreen
alias it claims to "mirror". If the rename lands, per-panel background settings
would silently stop being per-panel while the camera stayed per-panel. Resolve
the alias the same way in _bgPanelKey.
- drum_highway_3d: applyCamera()'s "before first positionCamera()" guard tested
`_camBaseH == null`, but _camBaseH/_camBaseD were initialized to 0, so the guard
never fired (and could apply a base-0 pose for a frame). Initialize to null.
- keys + drum: the PR claimed the Camera Director resolver was unit-checked, but
nothing exercised it. Extract the resolver into pure, exported helpers
(_resolveFreeCam + _ssApi), delegate the per-instance _freeCamFor to them, and
add tests/camera_bridge.test.js covering per-panel select, global fallback,
null-when-absent, throw-safety, and the slopsmith-alias resolution. Drum 15→21,
keys 50→56, all pass; behavior unchanged.
