WIP Remove jumper is support of command palette (#285)

* Remove jumper is support of command palette

* fix(command-palette): use replaceAll() for underscore-to-hyphen conversion in slug URLs

Addresses CodeRabbit suggestion: String.replace(/_/g, '-') is functionally
equivalent but replaceAll('_', '-') is more explicit and directly matches
the CodeRabbit suggestion for clarity.
