gsd-phase

Mode routing:

• default (no flag): Add a new integer phase to the end of the current milestone → add-phase workflow
• --insert: Insert urgent work as a decimal phase (e.g., 72.1) between existing phases → insert-phase workflow
• --remove: Remove a future phase and renumber subsequent phases → remove-phase workflow
• --edit: Edit any field of an existing phase in place → edit-phase workflow

Flag	Action	Workflow
(none)	Add new integer phase at end of milestone	add-phase
--insert	Insert decimal phase (e.g., 72.1) after specified phase	insert-phase
--remove	Remove future phase, renumber subsequent	remove-phase
--edit	Edit fields of existing phase in place	edit-phase

Parse the first token of $ARGUMENTS:

• If it is --insert: strip the flag, pass remainder (format: ) to insert-phase workflow
• If it is --remove: strip the flag, pass remainder (phase number) to remove-phase workflow
• If it is --edit: strip the flag, pass remainder (phase-number [--force]) to edit-phase workflow
• Otherwise: pass all of $ARGUMENTS (phase description) to add-phase workflow

Roadmap and state are resolved in-workflow via init phase-op and targeted reads.
