Add Thruster HTTP/2 proxy for improved performance

This commit integrates Thruster, a zero-config HTTP/2 proxy from Basecamp, to replace direct Puma --early-hints usage across all Procfiles.

Key changes:
- Add thruster gem to Gemfile
- Update all Procfiles to use "bundle exec thrust bin/rails server" instead of direct Puma with --early-hints
- Switch shakapacker from git branch to stable version 9.3.0
- Remove custom shakapacker build from npm postinstall script

Benefits:
- HTTP/2 support with automatic TLS termination
- Asset caching and compression
- Simplified configuration compared to manual early hints
- Better performance for static assets
