Publish source: Unlicense, public README, repo hygiene

The remote was previously a distribution-only point for pre-built DLLs.
This opens the source.

- LICENSE: Unlicense, with a GPL-3.0 carve-out for src/dpslog/WeirdDPSMate
  (a DPSMate fork that keeps its own license)
- README.md replaces the stale internal one with the user-facing docs from
  DLL_README.md, swapping the 'Why No Source Code?' section for build and
  layout notes. DLL_README.md is dropped; one README now serves both.
- RELEASING.md: drop the trim-the-README-per-release dance and the
  remote/WeirdUtils/ distribution clone, both obsolete now
- gitignore agent/editor scratch, build caches, the vendored WSBT addon,
  and the WeirdThreat/uwu-logs checkouts (separate upstream repos)
- Commit outstanding module work: superweirdo, clickthrough portal visuals,
  transform44 decompiles, worldmarkers demo presets, tools/

src/clickthrough/clickthrough.zig
