fix(honcho): honour contextTokens cap on summary/peer context calls

Salvage of #70951 (Willkons / Alice-Willk-bot). Two of three
session.context() sites never forwarded the configured cap, so Honcho
always returned honcho_chat_summary_long.

Adds the missing get_session_context tokens= regression the sweeper
asked for on that PR.
