refactor: remove Python sidecar setup from CI workflows

- Deleted the setup steps for creating a Python sidecar binary in both build.yml and package-and-publish.yml workflows.
- Removed the associated script for symlinking the system Python to the sidecar path, simplifying the CI configuration.
- Updated package installation steps to exclude Python dependencies, streamlining the build process.

-# Tauri sidecar binaries
-
-The app bundles a Python interpreter as a sidecar for skill runtimes (`runtime-skill-python`). The binary lives in `src-tauri/` (next to `tauri.conf.json`) and must be named by target triple.
-
-## Required file
-
-- **Python**: `src-tauri/runtime-skill-python-<TARGET_TRIPLE>` (e.g. `runtime-skill-python-aarch64-apple-darwin`, or `runtime-skill-python-x86_64-pc-windows-msvc.exe` on Windows)
-
-Get your target triple:
-
-```bash
-rustc --print host-tuple
-```
-
-## Local development (symlink to system Python)
-
-From the project root:
-
-```bash
-node scripts/setup-python-sidecar.mjs
-```
-
-This creates a symlink at `src-tauri/runtime-skill-python-<target>` pointing to your system `python3`.
-
-## Production / bundled Python
-
-For a standalone app that does not rely on the user having Python installed:
-
-1. **Windows**: Use the [Python embeddable package](https://www.python.org/downloads/windows/). Copy `python.exe` to `src-tauri/runtime-skill-python-x86_64-pc-windows-msvc.exe` (and the same for `aarch64-pc-windows-msvc` if you support ARM). You may need to bundle the rest of the embeddable folder as resources and set `PYTHONHOME` when spawning.
-
-2. **macOS / Linux**: Use [python-build-standalone](https://github.com/astral-sh/python-build-standalone/releases). Copy the `bin/python3` from the extracted tree to `src-tauri/runtime-skill-python-<target>`. Note: the binary may have dynamic library dependencies; for a fully portable build you may need to bundle the whole distribution as resources.
-
-After adding the binary, run `yarn tauri build` (or `yarn tauri dev`); the sidecar will be included in the bundle.
