chore(agents): add Rust code quality rules and skill (#3144)
* docs: update security advisory lessons * chore(agents): add Rust code quality rules and skill Add rules derived from full-project code review (48 findings across 7 dimensions) to prevent recurring issues in agent-generated code. AGENTS.md changes: - crates/AGENTS.md: error type design, concurrency, recursion safety, type casting, test quality rules - root AGENTS.md: serde safety, naming conventions - crates/ecstore/AGENTS.md: allocation discipline, lock ordering, recursion safety, dead code policy - crates/notify/AGENTS.md: lock ordering for runtime_view/facade Skill changes: - code-change-verification: add Rust-specific checks (unwrap, as cast, clone, lock order, recursion, error types, test assertions) - security-advisory-lessons: add serde deserialization safety pattern - NEW rust-code-quality: automated scan + manual review checklist

- Use environment variables or vault tooling for sensitive configuration.

- For localhost-sensitive tests, verify proxy settings to avoid traffic leakage.
|

|

## Serde Safety
|
||||
|
||||
- Add `#[serde(deny_unknown_fields)]` to structs deserialized from untrusted input (S3 API XML/JSON, lifecycle rules, bucket policies, replication configs).
|
||||
- When `deny_unknown_fields` is impractical (backward compatibility), at minimum log unknown fields at `warn` level.
|
||||
- Never use `#[serde(default)]` on security-critical fields without explicit validation of the resulting value.
|
||||
|
||||
## Naming Conventions
|
||||
|
||||
- Follow Rust API Guidelines for naming: `SCREAMING_SNAKE_CASE` for statics and constants, `snake_case` for functions and variables, `PascalCase` for types.
|
||||
- Do not use camelCase or Hungarian notation (e.g., `globalDeploymentIDPtr` → `GLOBAL_DEPLOYMENT_ID`).
|
||||
- If existing code violates naming conventions, do not widen the violation in new code. Fix opportunistically when touching the surrounding area.
