- Removed deprecated `helloworld` command.
- Expanded `update function` command with new options for Docker mounts, network restrictions, and various installation flags, including better error handling for boolean and number options.
- Introduced environment variable management commands: `add`, `list`, and `remove` for account-wide environment variables.
- Added `export` command to export authenticated account data.
- Implemented `api openapi` and `api request` commands for direct API interaction.
- Created logging and rate limit management commands for functions.
- Added MCP tool commands for calling tools, fetching documentation, and initializing sessions.
- Introduced utility functions for JSON handling and environment variable normalization.
- Set up CI/CD pipeline with Gitea Actions for automated testing, building, and publishing.
- Updated configuration loading to support environment variables for instance and token.
