Security, Compatibility, and Build Improvements#19
Conversation
- Enforced restrictive file permissions (chmod 600/700) for stored commands and configuration files to prevent unauthorized access. - Updated Pydantic v1 constructs (`@validator`) to v2 constructs (`@field_validator`) for compatibility with modern pydantic versions. - Fixed a Typer CLI bug where the welcome message was printed redundantly for subcommands. - Added `BUILD.md` and `docs/homebrew-command-storage.rb` suggesting the use of PyInstaller to distribute standalone binaries to avoid Homebrew source compilation overhead.

Code Review
This pull request introduces build and distribution documentation, adds PyInstaller as a development dependency, migrates Pydantic validators to the modern field_validator syntax, and implements restrictive file permissions for configuration and database files. It also refactors the CLI entry point to handle default behavior when no subcommand is invoked. Feedback on these changes highlights that the newly added Homebrew formula is currently non-functional due to an empty install method and incorrect source URL. Additionally, the direct use of chmod should be wrapped in try-except blocks to prevent failures on non-POSIX filesystems, and the Python version restriction to <3.13 in pyproject.toml should be reverted to support modern environments.

The newly added Homebrew formula is currently non-functional. The install method is completely empty (containing only comments), and the url points to the Python source package on PyPI which does not contain a pre-compiled cmds binary. If you want to distribute the pre-compiled binary (as recommended in BUILD.md), you should update the url to point to the release binary and implement bin.install "cmds" in the install method.

Calling chmod with Unix octal permissions like 0o700 or 0o600 can fail with an OSError on filesystems that do not support POSIX permissions (such as FAT32, exFAT, or certain network/Docker mounts). If this happens, the entire initialization will fail, making the application unusable. Wrapping the chmod calls in a nested try...except OSError block ensures that permission setting is attempted but failures due to filesystem limitations are handled gracefully.

Similar to the config file initialization, calling chmod on the database file can fail with an OSError on filesystems that do not support POSIX permissions (e.g., exFAT). Wrapping the chmod call in a nested try...except OSError block prevents filesystem limitations from failing the database creation entirely.

| db_path.write_text("{}") # Empty cmds dictionary | |
| # Set restrictive permissions to ensure security of stored commands | |
| db_path.chmod(0o600) | |
| except (json.JSONDecodeError, FileNotFoundError): | |
| db_path.write_text("{}") # Empty cmds dictionary | |
| # Set restrictive permissions to ensure security of stored commands | |

Restricting the Python version to <3.13 is an unnecessary regression from the previous ^3.9 specification. Python 3.13 is the current stable release and is fully supported by all dependencies in this project. Restricting it will prevent users on modern systems from installing the CLI tool.
