Add `make install` command to enable local builds for validators

[Jotatavo]

Description

Some validators prefer to build binaries locally from source code rather than downloading pre-compiled binaries. This ensures transparency, allows code auditing, and follows security best practices for critical infrastructure.

Proposal

Add a make install command to the repository that allows validators to:

1. Clone the repository
2. Build binaries locally from source code
3. Install the binaries on their servers

This would enable validators to:

• Review the code before compiling
• Build binaries in their own environments
• Have full control over the build process
• Meet security and compliance requirements

Benefits

• Increases validator trust in the software
• Aligns with open source best practices
• Facilitates adoption by validators with strict policies about pre-compiled binaries
• Enables source code auditing before installation

Technical Notes

The command should follow common conventions:

• make install to build and install
• Possibly include environment variables to customize install paths (e.g., PREFIX, DESTDIR)
• Document build prerequisites in DEVELOPMENT.md or README.md
