* Add Nixpacks configuration files to fix deployment detection error

- Added `package.json` to allow Nixpacks to detect the project as a Node.js application.
- Added `nixpacks.toml` to configure system dependencies (Python, Go, Docker client, etc.) and build phases, mimicking the original Dockerfile setup.
- Configured environment variables and paths to support OpenClaw execution in the Nixpacks environment.

* Fix Nixpacks build failures and deployment configuration

- Updated `nixpacks.toml` to:
  - Add `npm install` to `phases.install` to ensure dependencies (OpenClaw) are installed.
  - Add `--break-system-packages` to `pip3 install` command to comply with PEP 668 and fix build error.
  - Make `mkdir /data` and symlink commands non-fatal to accommodate different build environments (root vs non-root).
  - Update `[start]` command to include `node_modules/.bin` and `/app/scripts` in PATH, ensuring `openclaw` binary and scripts are found at runtime.
- Verified `scripts` directory content exists.
- This resolves the "Command execution failed" error during Nixpacks build.
Fixed a SQL injection vulnerability in `delete_sandbox.sh` and `create_sandbox.sh` by:
1. Enhancing `query_db` in `db.sh` to support parameterized queries via a Python 3 wrapper.
2. Updating `delete_sandbox.sh` and `create_sandbox.sh` to use the new parameterized query syntax.

This ensures all user-controlled input is safely handled by SQLite's parameter binding mechanism.

The try-except block in `skills/web-utils/scripts/scrape_browser_use.py` was effectively dead code because the `try` block only contained a `print` statement, which rarely fails.

This change:
1. Implements actual JSON validation using `json.loads()`.
2. Prints the result as-is if it's valid JSON.
3. Wraps the result in a `{"text": ...}` JSON object if it's not valid JSON.
4. Handles empty or `None` results gracefully.

This ensures that the script consistently outputs valid JSON for downstream consumers.
The `ensurepip` module attempts to install pip into the system Python environment, which is managed by Nix and is immutable. This causes the build to fail with an "externally-managed-environment" error.
Since `pip` is typically available in the python3 package provided by Nixpkgs or handled by `uv` later, this step is unnecessary and harmful in this context.

Removing this line allows the build to proceed to the next step, where dependencies are installed using `pip3 install --break-system-packages`.
The `python3 -m ensurepip` command fails in Nixpacks environments because the Python installation is externally managed and immutable (Nix store).
Additionally, the `pip3` command was not found in the PATH, causing the subsequent installation command to fail.

This change:
1. Removes `python3 -m ensurepip` to avoid the "externally-managed-environment" error.
2. Replaces `pip3 install` with `python3 -m pip install` to invoke pip reliably via the python interpreter.
The build server seemed to be using cached commands. This change:
1. Replaces `pip3 install` with `python3 -m pip install` to invoke pip reliably.
2. Adds a visible `echo` statement to the command list to ensure the build instruction hash changes, forcing a cache invalidation.
3. Removes `ensurepip` which is not supported in Nix environments.
