refactor: make debug functions public (single hyphen naming)

Renamed private debug functions to public API:
- wttrin--debug-show-log → wttrin-debug-show-log
- wttrin--debug-clear-log → wttrin-debug-clear-log

Added ;;;###autoload to both functions for proper autoloading.

Updated all references:
- README.org (2 occurrences)
- tests/README-DEBUG-TESTS.md (4 occurrences)
- tests/test-wttrin-integration-with-debug.el (8 occurrences)

These are user-facing commands that should be discoverable via M-x,
so they follow the public API naming convention (single hyphen).
