chore(deps): Wails v3 beta.20 to beta.22 lockstep

- go.mod, local CLI install, and @wailsio/runtime move together;
  the JS/Go wire protocol must match exactly, so the runtime never
  moves alone
- bindings regen is byte-identical (same 29 methods/IDs), confirming
  the bump is behavior-transparent at the binding layer
- beta.23 exists but is hours old and touches Linux single-instance;
  deliberately deferred to a routine bump, not stacked onto 2.0
- deletes wails.json (staged earlier during retirement proof; the
  version-source move lands in the next commit)
- svelte-check 0/0, vet/tests/builds green, smoke launch clean
