<objective> Manage phases in ROADMAP.md with a single consolidated command.

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

</objective>

<routing>

| 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 |

<context> Arguments: $ARGUMENTS

Parse the first token of $ARGUMENTS:

• If it is `--insert`: strip the flag, pass remainder (format: <after-phase-number> <description>) 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. </context>

<process> 1. Parse the leading flag (if any) from $ARGUMENTS. 2. Load and execute the appropriate workflow end-to-end based on the routing table above. 3. Preserve all validation gates from the target workflow. </process>
