wiki: document dev environment (WSL networking, workflow)

Capture hard-won dev knowledge that was only in commit messages:

- wsl-dev-networking: WSL2 NAT blocks UDP broadcast (device discovery can't
  reach the LAN); fix is mirrored networking (.wslconfig, Win11 22H2+), plus the
  gotchas that remained after — multiple interfaces, subnet-directed broadcast,
  localhost->IPv6 stall. Alternatives for non-mirrored setups.
- local-dev-workflow: first-time setup, pnpm dev, and the gotchas (the
  strip-types dev-server hang -> tsx, the 127.0.0.1 proxy fix, .env loading,
  seeding into the right DB).
- device-discovery: corrected the old "broadcast permission (EACCES)" note — the
  real cause was the lib not enabling SO_BROADCAST for global 255.255.255.255;
  documented the three verified broadcast gotchas + I/O serialization.
- schema: add a `reference` page type; new "Dev environment" index section; log.

Links lint clean; both new pages well-connected.
