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.

+# Topic Codes — registry for AyCode.Blazor's own topics (`ACBLAZOR`)
+
+Per the Framework-First Design Principle, this Layer 1 registry lists **only AyCode.Blazor's own (`ACBLAZOR`) topics**. Lower-layer (inherited) topics live in their own repos' registries — at runtime, the `docs-check` skill walks `own-dep-repos` from the invocation point to gather all inherited topics. AyCode.Blazor inherits from `AyCode.Core` (see this repo's `@repo.own-dep-repos`).
+
+Full ID format: `<PREFIX>-<TOPIC>-<TYPE>-<RAND>` — see `AyCode.Core/.github/REPO_PREFIXES.md` for the format spec.
+
+## ACBLAZOR topic codes
+
+| Code    | Topic                       | Scope                                                                             | Docs location                                                          |
+|---------|-----------------------------|-----------------------------------------------------------------------------------|------------------------------------------------------------------------|
+| `GRID`  | MGGRID (grid component)     | MgGrid component family: layout, CRUD, columns, toolbar, rendering                | `AyCode.Blazor.Components/docs/MGGRID/`                                |
+
+## Type codes (universal — see framework registry)
+
+Type codes (`I`, `T`, `B`, `C`, `DEC`) are universal across all repos and defined in the framework's `TOPIC_CODES.md` (`AyCode.Core/.github/skills/docs-check/references/TOPIC_CODES.md`). This file does not duplicate them.
+
+## ID format rules
+
+See the framework's `TOPIC_CODES.md` (`AyCode.Core/.github/skills/docs-check/references/TOPIC_CODES.md`) for the full ID format rules and Status conventions. This file only registers ACBLAZOR's own topic codes; ACCORE topics are inherited via this repo's `own-dep-repos`.
+
+## Examples (ACBLAZOR only)
+
+```
+ACBLAZOR-GRID-T-V4P7       # AyCode.Blazor's MgGrid TODO (e.g., "Generic ID generation in MgGridBase.SetNewId")
+ACBLAZOR-GRID-T-S2L9       # AyCode.Blazor's MgGrid TODO (e.g., "Implement local grouping")
+ACBLAZOR-GRID-I-XXXX       # placeholder for the first MgGrid issue once one is observed
+```
+
+## Adding a new ACBLAZOR topic
+
+1. Propose the code (2-5 uppercase chars), short and mnemonic, scoped to AyCode.Blazor's UI-framework domain.
+2. Check it doesn't collide with C# class-name prefixes (`Ac*` / `Mg*`).
+3. Check it doesn't collide with existing ACBLAZOR topic codes in the table above.
+4. Check it doesn't visually collide with framework (`ACCORE-*`) topic codes that this repo references — though the `<PREFIX>` component disambiguates, visual distinction helps readers.
+5. Add a row to the table above.
+6. Create the topic folder under the relevant project: `AyCode.Blazor.<Project>/docs/{TOPIC_FOLDER_NAME}/` with `README.md`, optional `{TOPIC_FOLDER_NAME}_ISSUES.md`, `{TOPIC_FOLDER_NAME}_TODO.md`.
+7. Optional: add an `LLMP-DEC-N` entry in the workspace-level `LLM_PROTOCOL_DECISIONS.md` if the new topic is workspace-meta-significant.
