refactor(pm): add catalog config support and rename init_project_root

[elrrrrrrr]

Summary

• Add [catalog] and [catalogs.*] TOML sections to Config struct via serde deserialization
• Add Config::catalogs() method and get_catalogs() accessor in user_config
• Rename update_cwd_to_root → init_project_root for clarity
• Unit tests for catalog parsing (default, named, empty, coexistence with config values)

Prerequisite for the catalog protocol feature (feat/pm-catalog-protocol).

Test plan

• cargo test -p utoo-pm -- util::config_file — 5 tests pass
• cargo clippy -p utoo-pm --all-targets -- -D warnings --no-deps — clean

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request primarily focuses on enhancing the project's configuration management system and improving code clarity. It introduces robust support for defining package catalogs through TOML configuration files, which is a foundational step for an upcoming catalog protocol feature. Concurrently, a key function responsible for initializing the project root has been renamed to better reflect its purpose, making the codebase more intuitive and maintainable.

Highlights

• Catalog Configuration Support: Introduced support for [catalog] and [catalogs.*] TOML sections within the Config structure, enabling more flexible catalog definitions.
• Catalog Accessor Methods: Added a Config::catalogs() method and a get_catalogs() accessor in user_config to retrieve parsed catalog configurations.
• Function Renaming for Clarity: Renamed the update_cwd_to_root function to init_project_root across the codebase for improved clarity and semantic accuracy.
• Unit Test Enhancements: Implemented comprehensive unit tests to validate the correct parsing of default, named, and empty catalog configurations, as well as their coexistence with other config values.

Changelog

• crates/pm/src/cmd/update.rs
  • Updated the import and usage of the project root initialization function.
• crates/pm/src/helper/workspace.rs
  • Renamed the update_cwd_to_root function to init_project_root.
  • Updated the documentation for the init_project_root function.
  • Adjusted the test case name to reflect the function rename.
• crates/pm/src/main.rs
  • Replaced all calls to update_cwd_to_root with init_project_root in the main command processing logic.
• crates/pm/src/service/install.rs
  • Modified the install service to use the newly named init_project_root function.
• crates/pm/src/util/config_file.rs
  • Extended the Config struct to include catalog and catalogs fields for TOML deserialization.
  • Added a catalogs() method to aggregate catalog data.
  • Refactored the load method to cache merged configurations and correctly handle local catalog merging.
  • Added new unit tests for catalog parsing, covering default, named, empty, and coexistence scenarios.
• crates/pm/src/util/user_config.rs
  • Introduced an asynchronous get_catalogs function to provide access to the parsed catalog configurations.

Activity

• The author confirmed that cargo test -p utoo-pm -- util::config_file passed 5 tests.
• The author confirmed that cargo clippy -p utoo-pm --all-targets -- -D warnings --no-deps ran cleanly.

Code Review

The pull request successfully refactors the update_cwd_to_root function to init_project_root, improving clarity and providing better documentation. It also introduces comprehensive support for catalog configurations, including default and named catalogs, with appropriate serde deserialization attributes and a new accessor method. While these changes contribute positively to the codebase, the implementation introduces significant security risks in the configuration management logic. Specifically, there is a potential for local project settings to pollute the global configuration file and a process-wide cache that leads to cross-directory configuration leaks. These vulnerabilities should be addressed by separating global and local configuration states and ensuring that the cache is directory-aware or avoided for merged configurations.
