feat(gsd-tools): add compound init commands and update workflows (#468)

* feat(gsd-tools): add compound init commands for workflow setup

Adds 8 compound commands that return all context a workflow needs in
one JSON blob, replacing 5-10 atomic calls per workflow:

- init execute-phase: models, config, phase info, plan inventory
- init plan-phase: models, workflow flags, existing artifacts
- init new-project: models, brownfield detection, state checks
- init new-milestone: models, milestone info
- init quick: models, next task number, timestamps
- init resume: file existence, interrupted agent
- init verify-work: models, phase info
- init phase-op: generic phase context

Updated 8 workflows to use compound commands:
- execute-phase, plan-phase, new-project, quick
- resume-project, verify-work, discuss-phase

Token savings: ~200 lines of bash setup replaced with single init calls.

* feat(gsd-tools): add 4 new init commands and update files to use compound commands

Add new compound init commands:
- init todos - context for todo workflows
- init milestone-op - context for milestone operations
- init map-codebase - context for codebase mapping
- init progress - context for progress workflow

Update 24 files to use compound init commands instead of atomic calls:
- 4 phase operation workflows (add-phase, insert-phase, remove-phase, verify-phase)
- 5 todo/milestone workflows (add-todo, check-todos, audit-milestone, complete-milestone, new-milestone)
- 6 misc workflows (execute-plan, map-codebase, pause-work, progress, set-profile, settings)
- 6 agent files (gsd-executor, gsd-planner, gsd-phase-researcher, gsd-plan-checker, gsd-debugger, gsd-research-synthesizer)
- 2 command files (debug, research-phase)
- 1 reference file (planning-config)

* fix(gsd-tools): add init to help output

* fix(verify-phase): correct expected init fields

The workflow was referencing plans/summaries from init phase-op,
but those fields come from ls command. Updated to reference
has_plans and plan_count which are actually in phase-op output.
