feat(goals): add GoalDecomposer — pure-logic task planner from mission+plugins
Introduces the GoalDecomposer class that bridges mission.strategy + plugin capabilities into concrete, weighted Task objects. Each Task has a target screen, budget, weight, and human-readable intent. Key design decisions: - Pure logic, zero LLM/device dependencies - Strategy weights (aggressive_growth, community_builder, etc.) drive selection - Plugins declare which screens they operate on (multi-screen map) - Screens need BOTH an action route AND active plugin to be viable - Frozen dataclass ensures Task immutability 12/12 TDD tests passing.

GoalDecomposer — Mission-Driven Task Planning
|
||||
|
||||
Translates the bot's `mission` config + `plugins` capabilities into
|
||||
concrete, weighted Task objects. Pure logic — no LLM, no device,
|
||||
no network, no side effects.
|
||||
|
||||
This is the bridge between:
|
||||
- "What does the user WANT?" (mission.strategy)
|
||||
- "What CAN the bot DO?" (enabled plugins + actions)
|
||||
- "What SHOULD it do NOW?" (weighted Task selection)
|
||||
|
||||
Tesla analogy: FSD doesn't have a "goal: drive safely" config.
|
||||
It derives behavior from destination + road rules + sensor capabilities.
