thrunt-remove-phaselisted

<objective> Remove an unstarted future phase from the huntmap and renumber all subsequent phases to maintain a clean, linear sequence. Purpose: Clean removal of work you've decided not to do, without polluting context with cancelled/deferred markers. Output: Phase deleted, all subsequent phases renumbered, git commit as historical record. </objective> <execution_context> @.github/thrunt-god/workflows/remove-phase.md </execution_context> <context> Phase: $ARGUMENTS Huntmap and state are resolved in-workflow via `init phase-op` and targeted reads. </context> <process> Execute the remove-phase workflow from @.github/thrunt-god/workflows/remove-phase.md end-to-end. Preserve all validation gates (future phase check, work check), renumbering logic, and commit. </process>
