BUG: matcha update fails with permission denied when writing temp binary to /usr/local/bin

[OverStyleFR]

Describe the bug

When running the matcha update command as a standard user, the update fails because it attempts to create the temporary binary file directly in the installation directory (/usr/local/bin/), which requires root privileges.

To reproduce

Steps to Reproduce:

1. Have matcha installed in a directory that requires root privileges (e.g., /usr/local/bin).
2. Run the update command as a standard user: matcha
3. The download starts but fails at the file creation step.

Actual Behavior

The updater tries to write the temp file directly to the target directory and throws a permission error:
Plaintext

> matcha update
Current version: 0.36.1
Latest version: 0.37.0
Found release asset: matcha_0.37.0_linux_amd64.tar.gz
Downloading...
update failed: could not create temp binary in target dir: open /usr/local/bin/matcha.new.1778155730: permission denied

Expected behavior

Expected Behavior / Proposed Solution

Instead of attempting to write directly to the protected target directory, it would be more logical for the updater to:

Download the temporary file to `/tmp/`.

Then, either prompt the user for `sudo` privileges to move the binary into `/usr/local/bin/`, or exit gracefully with a clear message instructing the user to run the update command with `sudo` (e.g., Please run 'sudo matcha update`').

Thank you for the suggestion, for time being the fix, that should work, is granting yourself access to the folder (which you should have had)

sudo chown -R $(whoami) /usr/local/bin
