refactor: rename planning terminology to plan

Rename 'planning' to 'plan' throughout the codebase to match OpenCode's
built-in agent naming conventions (plan, build, evaluation).

Changes:
- planningModel → planModel (config, types, CLI)
- --planning-model → --plan-model (CLI flag)
- OPENCODER_PLANNING_MODEL → OPENCODER_PLAN_MODEL (env var)
- Phase 'planning' → 'plan' (types, state)
- generatePlanningPrompt → generatePlanPrompt (plan.ts)
- generateIdeaPlanningPrompt → generateIdeaPlanPrompt (plan.ts)
- runPlanning → runPlan (builder.ts)
- runIdeaPlanning → runIdeaPlan (builder.ts)
- runPlanningPhase → runPlanPhase (loop.ts)
- Updated all docs, tests, and example config
- Updated release.yml workflow for Bun cross-compilation

 ### The Philosophy
 
-OpenCoder treats software development as an **infinite game**. There's always another test to write, another edge case to handle, another optimization to make. OpenCoder embraces this by never declaring "done"—it continuously cycles through planning, building, and evaluation until you tell it to stop.
