aider: fix inconsistent --type flag and enable task reporting #739

Problem

start.sh has two branches in start_agentapi(): one for when an initial prompt is provided, one for when it isn't. Only the prompt branch passes --type aider to agentapi server. The no-prompt branch omits it, causing agentapi to fall back to generic terminal output parsing.

Separately, report_tasks defaults to false, which means Aider tasks don't get activity-based TTL bumps even though the text-based reporting plumbing exists.

To see the bug: start the module without setting ai_prompt and inspect the agentapi process args. --type aider will be missing.

Desired outcome

• --type aider is passed to agentapi server regardless of whether an initial prompt is set.
• report_tasks defaults to true.

Constraints

This ticket does NOT add session resume or enable_state_persistence. Aider's --restore-chat-history flag performs lossy reconstruction from a markdown log, frequently crashes on large histories, and doesn't restore file context. It is the only agent where enable_state_persistence = false is the correct long-term setting. Aider also lacks MCP support (start.sh has a TODO for this).
