fix: prevent planner from generating invalid verification types (#1388) (#1529)

The planner agent was generating invalid verification types like `code_review`
because the prompt didn't explicitly constrain allowed types or document all
valid options.

Changes:
- Add explicit warning in planner.md that ONLY 6 types are valid
- Document all 6 verification types (was missing `none`)
- Add guidance: use `manual` for code review, `command` for tests
- Add `manual` and `none` verification instructions to coder.md
- Add handlers for `e2e`, `manual`, `none` in checklist_generator.py
- Add missing schema fields: `command`, `expected`, `instructions`
- Mark `component` as legacy (kept for backward compatibility)

Fixes #1388
