v0.6.41

Changed

• Internal refactor: src/tools/write.ts (6,828 lines) is split into cohesive src/tools/write-*.ts modules (schema, response notes, source resolution, classrun-bridge create/delete/update/index/search-help handlers, package create, batch delete). No behaviour change: the abap_write schema, description and every response string are unchanged, and tools/list output is byte-identical.
