fix: Install script now uses release tag instead of main branch (#75)

Problem: Even though the website fetched install.sh from a specific release tag,
the script itself would clone the repository from main branch, installing
potentially unstable/untested code.

Solution:
- Add --tag parameter to install.sh to specify which release to install
- Default to v0.3.0-alpha (latest stable) instead of main
- Clone the specific tag using 'git clone --branch <tag>'
- Update website to pass --tag parameter with fetched release

Changes:
- install.sh: Add --tag parameter, default to v0.3.0-alpha, clone specific tag
- web/src/app/page.tsx: Pass --tag=<version> to install script

This ensures users install the exact release version they intended, not
whatever code is currently on main branch.
