- 36 files move into the module whose AGENTS.md already claimed them:
Engine/, Synth/, Modulation/, Params/, Plugin/, GUI/, EffectUnits/, Resources/
- Source/engine, modulation, params, plugin and synth become Engine,
Modulation, Params, Plugin and Synth, matching the directories that already
hold code
- ExactCompare.h stays at the Source/ root as the one shared header
- SERUMALT_INCLUDE_DIRS adds one include directory per module, so the 31
parent-relative includes become plain names with no path prefix
- the module AGENTS.md files list owned files instead of describing a move
that had not happened, and README.md and AGENTS.md describe the real tree
Verified: the harness passes CTest, the Linux VST3 and Standalone link, the
Windows cross-build passes its module checks, each configure exposes only its
own targets, no first-party warning line appears, and the generated Windows
manifest is unchanged.
