docs: update all documentation for new dot command interface

Replace all legacy command references with new unified `dot` syntax
throughout documentation. Remove backward compatibility sections and
streamline examples to use modern command structure.

Changes:
- README.md: Update command interface section with new syntax
- INSTALLATION.md: Replace legacy commands in examples
- ONE_LINE_INSTALL.md: Update verification commands

All examples now use intuitive `dot <action>` format instead of
fragmented `dotcommand` aliases.
