Crucible: Fix Formatting Churn (#5)

RC#1 — build wrote 2-space instead of .editorconfig's 4-space
- editorconfig_format.go: the glob translator escaped {/} as literals, so [*.{json,jsonc}]→indent_size=4 never matched any file and formatting fell back to [*]→2. Implemented real editorconfig brace expansion — {a,b,c} alternation and {n..m} numeric ranges. Nothing is hardcoded; saveLockfile already read .editorconfig, it just got the wrong section.

RC#2 — validate wrote a lockfile (it must be read-only)
- The three registry collectors persisted lockfiles as a side effect of collection; ValidateProject calls collection outside its snapshot guard, so the write leaked. Threaded a persistLocks bool through collectGeneratedRegistryDatasets and the damagetypes/itemprops/racialtypes collectors. Only buildNativeUnchecked (the real build allocator) passes true; validate, discovery, packaging queries, and wiki discovery pass false.

Tests added: editorconfig_glob_test.go (brace match + 4-space via brace glob), registry_readonly_test.go (read-only writes nothing; persist writes allocations).

+## Quick start (no Nix)
+
+Teammates without Nix don't build anything — they run the bootstrap wrapper,
+which downloads the latest released `crucible` for your OS and runs it:
+
+```bash
+./crucible            # interactive menu (pick a command)
+./crucible module build
+./crucible topdata validate-topdata
+```
+
+Windows (PowerShell):
+
+```powershell
+.\crucible.ps1 module build
+```
+
+The binary is cached under `~/.cache/crucible/<version>/` (`%LOCALAPPDATA%\crucible`
+on Windows); `--repo-local` caches inside the repo instead. Private releases:
+set `CRUCIBLE_TOKEN` or write the token to `~/.config/crucible/token`.
+
+Only the **music** builder needs `ffmpeg`; everything else has zero dependencies.
+If you run a music command without it, Crucible prints a per-OS install hint.
