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/

+# MPQ Load Order — WoW 1.12.1
+
+`MPQ_InitializeArchives` (0x403740) loads in two phases.
+
+## Phase 1 — Base archives (loaded by index)
+
+Filename table at `0x82e12c`:
+
+| Index | Archive |
+|-------|---------|
+| 0 | model.MPQ |
+| 1 | texture.MPQ |
+| 2 | terrain.MPQ |
+| 3 | wmo.MPQ |
+| 4 | sound.MPQ |
+| 5 | misc.MPQ |
+| 6 | interface.MPQ |
+| 7 | fonts.MPQ |
+| 8 | speech.MPQ |
+| 9 | dbc.MPQ |
+| 10 | speech2.MPQ |
+
+Each opened via `OpenMPQArchiveWithPaths` (0x403b00) which tries `Data\name` then `..\Data\name`.
+
+## Phase 2 — Patch archives
+
+- `MPQArchiveEnumerator` (0x4039b0) discovers `patch-?.MPQ` files via glob
+- Then opens `patch.MPQ` and any discovered `patch-X.MPQ` archives
+
+## Search order at file lookup time
+
+`File_FindInArchive` (0x6549a0) searches the global archive array at `0x8826b4` recursively — later-registered archives (patches) are checked first. The array is searched from `count-1` down to `0`, so patches override base content.
+
+## Global archive array
+
+```
+Struct at 0x8826b4:
+  +0x00 [0x8826b4]: capacity
+  +0x04 [0x8826b8]: count
+  +0x08 [0x8826bc]: array_ptr (SArchive**)
+  +0x0C [0x8826c0]: growth_incr
