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).
