Updated all docs, skills, and examples to use year-month archive files (`*_<YYYY>_<MM>.md`) for `_ISSUES.md`, `_TODO.md`, and `LLM_PROTOCOL_DECISIONS.md`. Decision Log rolling window now governed by LLMP-DEC-67 (last 15 entries active). Clarified archive file handling, updated uniqueness checks, and revised references throughout. Closed and documented resolution for `FBANKAPP-DMODEL-I-P6X4` in `DATAMODEL_ISSUES.md`.
Update ID format to use per-repo prefixes and random suffix
Migrated all issue, TODO, and decision IDs to a new 4-part format: <PREFIX>-<TOPIC>-<TYPE>-<RAND>. Added per-repo prefix declarations in copilot-instructions.md and documented conventions in REPO_PREFIXES.md. Updated all topic registries, logs, cross-references, and documentation to use the new format. Introduced MIGRATION_ID_MAPPING.md for old-to-new ID mapping. Enhanced skills and protocol audit logic to validate and enforce per-repo prefixes and topic codes at runtime. Clarified Framework-First doctrine and ensured all references are unambiguous.
