Fixes #1186

Summary

• Schedule the existing retitle hook for human replies delivered through Ebi AI Console.
• Preserve the raw human reply separately from long-text and attachment instructions added for the agent; generated skill prompts do not trigger retitling.
• Add regressions for the retitle source and transformed long-text/attachment delivery path.

Verification

• Red-green regression tests — both focused tests first failed against the old behavior/interface, then passed after the fix.
• pytest tests/test_console_server.py -q — 24 passed.
• make check — 429 files formatted; Ruff passed.
• Full suite pytest tests -q --cov=claude_discord — 4,610 passed, 9 skipped, 3 failed. The same three failures were reproduced on clean base 849afed: test_dry_run_leaves_removable_worktree_on_disk, test_live_cleanup_preserves_work_and_unmerged_branches[clean], and test_the_prompt_keeps_the_latest_messages_and_states_the_time. No changed-file failure.
