Dev notes mode

Controls when aidev asks the task provider for clarification before implementing.

Mode	Behaviour
smart	Asks the AI whether the task description is clear enough. Only posts a clarification question if it's ambiguous.
always	Always posts "any dev notes?" before implementing every task.

When a question is posted, the task is moved to the configured pending status (e.g. CLICKUP_PENDING_STATUS, JIRA_PENDING_STATUS, etc.). On the next run, aidev checks whether a human has replied and, if so, includes the reply as context for the AI.

Configure via DEV_NOTES_MODE in .env.aidev.
