Adds an optional focus topic to /compress: `/compress database schema` guides the summariser to preserve information related to the focus topic (60-70% of summary budget) while compressing everything else more aggressively. Inspired by Claude Code's /compact <focus>. Changes: - context_compressor.py: focus_topic parameter on _generate_summary() and compress(); appends FOCUS TOPIC guidance block to the LLM prompt - run_agent.py: focus_topic parameter on _compress_context(), passed through to the compressor - cli.py: _manual_compress() extracts focus topic from command string, preserves existing manual_compression_feedback integration (no regression) - gateway/run.py: _handle_compress_command() extracts focus from event args and passes through — full gateway parity - commands.py: args_hint="[focus topic]" on /compress CommandDef Salvaged from PR #7459 (CLI /compress focus only — /context command deferred). 15 new tests across CLI, compressor, and gateway.
