fix(supervisor): ensure all implementation phases are executed before PR (#53)

Previously the supervisor would implement only the first phase of a
multi-phase plan and then create a PR. This change updates the supervisor
system prompt to explicitly instruct it to:

1. Read and parse plan documents for multiple implementation phases
2. Execute phases sequentially
3. Track completion of each phase
4. Only create PR after ALL phases are complete
