add /system-prompt command to show the exact prompt sent to the model

[kevinjosethomas]

• adds a /system-prompt slash command that prints the exact system prompt the model receives for the current session, verbatim, so it's easy to see what skills, harness state, and context are actually being sent.
• plumbs a getSystemPrompt call through the in-process, daemon, and deferred connection layers, mirroring the existing getLastAssistantText path.
• falls back to building the current prompt when the session hasn't run a turn yet, since the stored prompt is empty until the first turn.

Note

Low Risk
Read-only introspection and a new daemon query command; no changes to prompting, auth, or session mutation paths.

Overview
Adds a /system-prompt builtin slash command so you can inspect the exact system prompt the model sees for the current session (skills, harness, per-turn extension overrides).

AgentConnection.getSystemPrompt() is wired the same way as getLastAssistantText: in-process reads session.systemPrompt, the daemon adds get_system_prompt (read-only, does not invalidate attach snapshots), and DeferredAgentConnection returns an empty string until a real session exists.

Interactive mode handles the command with no args and prints a titled block in the chat, including character count.

Note

Add /system-prompt slash command to display the current system prompt in the chat UI

• Adds a /system-prompt command that fetches and displays the active system prompt (with its character count) in the chat UI via InteractiveMode.handleSystemPromptCommand().
• Extends the AgentConnection interface with getSystemPrompt(), implemented across in-process, daemon-backed, and deferred connections.
• The daemon handles a new get_system_prompt command type that looks up the prompt by session ID without invalidating the cached snapshot.
