Revise the Markdown docs against the code and the fork's state

Checked every claim that names a setting, default, log line, binding or
script against the source, and brought the docs up to date with the
Steam Frame build:

- README: the recommended settings show their Frame defaults (render
  scale 0.8, resolution multiplier 1) and add eye-tracked foveation and
  the refresh rate; the settings panel's gamepad-mode button (both
  sticks); by-hand release tags moved to frame-beta-2; the AI usage note
  points at a section that exists.
- OPENXR.md: the intro and requirements cover all three backends; the
  Linux Vulkan backend, its patched Dawn and time conversion; Frame
  defaults for render scale and culling; the Frame controller profile in
  the binding list and limitations; foveation on the Frame and its
  per-map memory; scope of passthrough and tracked hands; Linux log path.
- quest-port.md: Known gaps rewritten (it still said the app had not run
  on a Quest, foveation was off by default, haptics unused and the pack
  not downloadable); intro names every product sharing the spec.
- DISTRIBUTION.md: how this fork's source-only frame-* releases are made.
- THIRD-PARTY-NOTICES.md: libco's aarch64 backend, Dawn built from source
  for the Quest and the Frame, and the tools the Frame installer fetches.
- CONTRIBUTING, RELEASE_VALIDATION, android/README, translator/README,
  building-macos: fork context, broken pointers, list formatting, typos.
- aurora-main/README: drop a screenshot that was not vendored.

All relative links and anchors resolve.
