[LOADED_DOCS: 3 files, no new loads]

Refactor SIGDS docs, archive DEC log, add pipe tests

- Updated all references to AcSignalRDataSource docs to new SIGNALR_DATASOURCE/README.md location; introduced SIGDS topic and paired issues/TODO files.
- Implemented new Decision Log archival policy: last-15-active entries remain, older entries moved to year-month archive (LLMP-DEC-65, 67); updated docs-archive skill for two-rule rotation.
- Added new SIGDS architectural TODO (ACCORE-SIGDS-T-D9F2) for relocating DataSource code.
- Updated doc tables, glossaries, and conventions for SIGDS.
- Added AcBinarySerializerPipeParallelTests.cs for parallel serialization/deserialization round-trip tests.
