refactor(block): migrate block data to JSON and resource locations

Replace TOML block definitions with JSON files loaded from asset locations. Block names are now ResourceLocation keys, IDs are resolved from registry.json, and reusable JSON parsing helpers were added.

+# Code Modification Guidelines
+
+## 1. Git Branch Protection
+
+- Never modify code directly on the `main` branch.
+- Before editing, check the current branch:
+
+```bash
+git branch --show-current
+````
+
+* If the result is `main`, create or switch to a development branch first:
+
+```bash
+git checkout -b feature/xxx
+```
+
+* Do not bypass branch protection by:
+
+  * Committing directly to `main`.
+  * Running code generation, formatting, or large refactors on `main`.
+  * Rewriting or damaging `main` history.
+
+---
+
+## 2. Code Comments
+
+* All new comments must be written in English.
+* Comments must be:
+
+  * Short and clear.
+  * Explain the purpose, not repeat the code.
+  * Avoid unnecessary details.
+
+Recommended:
+
+```cpp
+// AI-generated: Prevent stale handle access.
+```
+
+Avoid:
+
+```cpp
+// AI-generated: This checks if the handle is invalid because...
+```
+
+* Important AI-added or modified logic should include:
+
+```cpp
+// AI-generated
+```
+
+* Do not add comments for trivial changes such as:
+
+  * One or two line logic fixes.
+  * Spelling corrections.
+  * Simple variable renames.
+
+### 2.1 Do not write excessive or granular comments
+
+AI must avoid sprinkling small explanatory comments throughout code.
+Specifically:
+
+* **No line-by-line narration.** Do not add a comment above (or beside)
+  every field, signal, slot, branch, or block just to restate what it is.
+  If the name is self-explanatory, no comment is needed.
+* **No multi-part explanations on a single marker.** A line like
+  `// AI-generated: abort the in-flight download; finished handler clears state.`
+  is too much. Either drop it, or shorten to a single short clause
+  (e.g. `// AI-generated: abort in-flight download.`).
+* **Prefer zero or one comment per file/section**, not many. A short
+  header comment explaining the file's purpose is acceptable; dozens of
+  inline labels are not.
+* **Do not comment obvious QML/C++ bindings, layout splits, or default
+  values** (e.g. `// AI-generated: index 0 -> zh_CN, index 1 -> en.`).
+  The code already says that.
+* **When in doubt, omit the comment.** A missing comment is fine; a
+  redundant one is noise that future maintainers must clean up.
+
+Rule of thumb: if removing the comment would not lose useful
+information, remove it.
+
+---
+
+## 3. Project Style
+
+Follow the existing project style strictly:
+
+* Naming conventions.
+* File organization.
+* Formatting rules.
+* Include order.
+* Existing architecture.
+
+Do not:
+
+* Introduce unrelated coding styles.
+* Add unnecessary design patterns.
+* Create duplicate systems.
+* Add abstractions without need.
+* Change module responsibilities.
+
+---
+
+## 4. Modification Scope
+
+Only modify the minimum code required.
+
+Do not:
+
+* Format unrelated files.
+* Remove existing comments.
+* Rename large numbers of symbols.
+* Change public APIs.
+* Perform large refactors without confirmation.
+
+If large changes are required, explain first:
+
+1. Current problem.
+2. Required changes.
+3. Affected modules.
+4. Expected impact.
+
+---
+
+## 5. Build and Test
+
+After modifications:
+
+* Verify compilation.
+* Check for new warnings.
+* Ensure existing features still work.
+
+Do not:
+
+* Commit without verification.
+* Ignore compiler errors.
+* Hide problems with temporary hacks.
+
+---
+
+## 6. Compatibility
+
+Consider:
+
+* Existing callers.
+* API/ABI compatibility.
+* Serialization formats.
+* Network protocols.
+* Save data.
+* Threading impact.
+
+Do not:
+
+* Change network structures without compatibility handling.
+* Break old data formats.
+* Change public data layouts carelessly.
+
+---
+
+## 7. Multi-threading Safety
+
+For multi-threaded code, check:
+
+* Data races.
+* Object lifetime.
+* Lock contention.
+* Atomic correctness.
+* Cross-thread resource access.
+
+Do not:
+
+* Assume single-threaded execution.
+* Modify shared data without protection.
+* Add hidden locks that hurt performance.
+
+---
+
+## 8. Memory Safety
+
+Consider:
+
+* Ownership.
+* Lifetime.
+* RAII.
+* Memory leaks.
+* Dangling references.
+* Iterator invalidation.
+
+Do not:
+
+* Return references to local variables.
+* Store pointers to temporary objects.
+* Use uninitialized data.
+* Introduce undefined behavior.
+
+---
+
+## 9. Third-party Libraries
+
+Before adding or changing dependencies:
+
+Check:
+
+* Existing project dependencies.
+* Build system impact.
+* Maintenance cost.
+
+Do not:
+
+* Add large libraries for simple features.
+* Duplicate existing library functionality.
+* Modify third-party source code.
+
+---
+
+## 10. AI Behavior Rules
+
+AI-generated code must:
+
+* Reuse existing code first.
+* Preserve current architecture.
+* Prefer simple solutions.
+* Minimize risk and code changes.
+
+Do not:
+
+* Guess requirements.
+* Add unrequested features.
+* Redesign architecture.
+* Add unnecessary abstraction layers.
+
+Choose the implementation with:
+
+> The smallest change, lowest risk, and best compatibility with existing code.
+
+---
+
+## 11. Pre-commit Checklist
+
+Before committing:
+
+* [ ] Not on `main`.
+* [ ] Changes match the requested task.
+* [ ] New comments are in English.
+* [ ] AI changes are marked when needed.
+* [ ] No unrelated formatting changes.
+* [ ] Build passes.
+* [ ] No obvious performance/security/thread issues.
+* [ ] No API, protocol, or data format breakage.
