test: add comprehensive test scripts for terminal command tag handling
- test_terminal_commands.js: Tests regex pattern matching, parser logic, and content splitting - test_dyad_parser.js: Integration test for DyadMarkdownParser terminal command handling - Both tests verify that terminal command tags are parsed correctly but not displayed in UI - Tests confirm commands execute silently in terminals while preserving markdown content - All tests pass, confirming the fix works correctly
