## 0.4.0 — 0.4 path break: engine, catalog, and generation

Source modules now live under src/engine, src/catalog, and src/generation. morph_engine.js and morph_analyze.js are morph-engine.js and morph-analyze.js. Deep imports on the published archive follow that layout (/api/v0.4-latest/engine/morph-engine.js). v0.3-latest stays the frozen 0.3 line and is not rewritten. Package subpaths oq-api/engine, oq-api/catalog, and oq-api/generation export the direct modules; the package root still clones shared results. setActiveLocale and getActiveLocale are removed: pass options.locale or the third argument of t(), and an omitted locale is English. searchEntries no longer accepts positional match, rank, or regex arguments; pass an options object. A string options value throws.
