feat: DorkNet.Quest, a sideload patcher for the 2023 Quest client

Patches the Quest build of Rec Room 2023.03.21 (20230317 / 2128210, the
same appVersion as the PC client) to connect to a DorkNet server, using
one native hook library loaded via DT_NEEDED on libmain.so.

- host rewrite onto <svc>.<ServerHost> or a {service}-dev.example.com template
- Photon app ids and region injection (PhotonRegion must match PC)
- TLS / pinning / image-signature bypass, integrity callbacks neutralised
- no-Meta-account build; the server treats platform id 0/1/blank as a
  placeholder and keys those accounts by device id
- build.ps1 -Obb packages a DorkNet-<ver>.xapk with one-command
  installers for Windows and macOS/Linux; app is named via AppName
- README, docs/quest.md and NOTICE updated; credits RecFlare and
  And64InlineHook (MIT)

Tested on a Quest 2: all hooks arm, requests reach the dev server.

+"""Add a DT_NEEDED entry to libmain.so so the Android loader pulls in
+libdorknet.so before Unity starts.
+
+libmain.so is tiny (the Unity bootstrap shim) and lists libil2cpp etc. as
+DT_NEEDED; adding one more makes the loader map our hook library first. This is
+the same mechanism RecFlare uses on Quest. Idempotent: a second run is a no-op.
