Unify the two CLI applications into one

[Hell1213]

Description

The project currently has two parallel CLI applications: oss-dev (Click-based, legacy) and oss-dev-new (Typer-based, modern). Having two entry points is confusing for users. Refactor to consolidate into a single CLI.

Tasks

• Audit which legacy commands in oss-dev are still needed vs. already covered by oss-dev-new
• Migrate any missing functionality from Click to Typer CLI
• Remove oss-dev entry point from pyproject.toml
• Rename oss-dev-new to oss-dev
• Update all documentation references
• Verify all existing tests still pass

Skills Required

• Python
• Click and Typer CLI frameworks
• Refactoring
