fix(prompts): render AGENT_SYSTEM_PROMPT_3's Time line per call

The prompt was a module-level f-string, so get_time() ran once at import
and every agent was told the process start time. The default parameter in
Agent.__init__ froze it a second time, since defaults evaluate at def time.

Split the text into timeless header and body, add build_agent_system_prompt()
to render the Time line on demand, and resolve the default inside __init__.

Fixes kyegomez#2131
