fix: guard PSI/module resolution with read lock in notifyElementModifiedForPath

psiManager.findFile / structureProvider.getModule / findModuleForSourceId ran
without holding the read lock, so they could race a concurrent `analyze` read
section. Resolve them inside project.read { } (mirroring loadKtFile) and hand
the results to the existing project.write { } mutation block.
