[TsingShui]

Summary

• Add a default-enabled, optional mcp feature and a rust_ASC mcp stdio server for CodeMode and standard MCP clients.
• Expose four read-only tools: getclass, listclass, getmanifest, and findrefs, with typed schemas, structured results/errors, and absolute local input paths.
• Bound query concurrency and support cooperative cancellation. Share input normalization and analysis with the CLI while preserving its direct string-output path.
• Document installation and a generic client configuration. Existing CLI commands and CI configuration are unchanged; --no-default-features excludes MCP and its dedicated dependencies.

Validation

• Release tests: 67 passed with default features; 57 passed with --no-default-features.
• Explicit MCP feature check: cargo check --locked --no-default-features --features mcp.
• Clippy: cargo clippy --all-targets --locked -- -A clippy::uninit_vec (allowance for the existing loader implementation).
• Real Pi CodeMode smoke test, including concurrent queries and structured errors.
• CLI output equivalence against upstream on two real APKs, with and without MCP enabled.
• cargo install --path . --locked verified using an isolated installation root.

Scope

Queries are stateless and return complete results: no HTTP/SSE, server-side JavaScript, CLI subprocess wrapper, export, cache, or pagination. Cancellation is cooperative; this does not add hard deadlines or parser crash isolation.
