feat: enhance function execution options and logging capabilities

- Added `--route` and `--method` options to `function execute` command for better HTTP handling.
- Improved `get function` command to display additional function metadata including HTTP settings, cache status, network restrictions, RAM limits, timeouts, and tags.
- 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.

+# Claude Notes for SHSF CLI
+
+Work from current evidence. The sibling repo `../shsf` is the source of truth for SHSF backend routes and MCP behavior.
+
+## Fast Orientation
+
+- CLI source: `src`
+- Command loader: `src/commands.ts`
+- REST client: `src/api.ts`
+- Config: `src/config.ts`
+- Tests: `src/__tests__`
+- Gitea CI/CD: `.gitea/workflows/ci.yml`
+
+## Backend Checks
+
+When updating route support, inspect these files in `../shsf`:
+
+- `Backend/src/routes` for REST paths and request schemas
+- `Backend/src/routes/mcp.ts` and `Backend/src/lib/mcp` for MCP behavior
+- `Backend/src/lib/aidoc.ts` for function-authoring rules returned by `get_docs`
+
+Do not infer backend payloads from old CLI code when the backend source is available.
+
+## Agent Workflow
+
+Use these commands for discovery:
+
+```bash
+shsf api openapi
+shsf mcp init
+shsf mcp tools
+shsf mcp docs
+```
+
+Use `shsf api request <method> <path>` for live REST endpoints that do not yet have typed wrappers.
+
+Before writing SHSF function code, call `shsf mcp docs` or the MCP `get_docs` tool and follow the returned platform rules.
+
+## Verification
+
+Run:
+
+```bash
+pnpm test
+pnpm build
+```
+
+Keep changes scoped. Do not reintroduce removed GitHub workflow metadata, editor-specific instruction files, or skill markdown files unless explicitly requested.
