fix(gateway): resume numbered session search results

[GodsBoy]

What does this PR do?

Gateway session numbers now refer to the latest numbered session list shown in that same chat. After /sessions search <query> returns old matching sessions, /resume <number> resumes the row the user picked instead of re-querying the unrelated default recent /resume list.

The remembered rows are scoped by gateway session key, bounded to the 10 displayed choices, and stored only after the existing visibility filtering. Final resume authorization is unchanged: the selected id still flows through continuation resolution, Matrix room checks, owner checks, and the existing switch path.

Type of Change

• Bug fix (non-breaking change that fixes an issue)
• New feature (non-breaking change that adds functionality)
• Security fix
• Documentation update
• Tests (adding or improving test coverage)
• Refactor (no behavior change)
• New skill (bundled or hub)

Changes Made

• gateway/slash_commands.py: remember the latest numbered gateway session list per session key and resolve numeric /resume against it before falling back to the old bare /resume behavior.
• hermes_cli/session_listing.py: clarify the gateway listing footer so numbers are documented as coming from the latest session list, not only from /resume.
• tests/gateway/test_resume_command.py: cover numbered resume from /sessions search, out-of-range search choices, stale no-result searches, and cross-chat isolation.

How to Test

1. In a gateway chat with old matching sessions outside the default recent list, run /sessions search <query>.
2. Send /resume <number> using a number from that search result.
3. Hermes should resume the session shown at that number.

Local verification:

scripts/run_tests.sh tests/gateway/test_resume_command.py tests/hermes_cli/test_session_listing.py -q
/root/clawd/repos/hermes/.venv/bin/python -m py_compile gateway/slash_commands.py hermes_cli/session_listing.py tests/gateway/test_resume_command.py

Manual validation:

• Patched the VPS install and confirmed in a Telegram bound topic that /sessions search <query> followed by /resume <returned number> resumes the selected old session.
• I did not restart the gateway again after that manual validation.

Thanks for tracing the search/list and numeric-resume mismatch; current main still has that mismatch in gateway/slash_commands.py:3616-3629, so the fix direction is valid.

Problems

• In the PR head, bare /resume returns for an empty titled list at gateway/slash_commands.py:3605-3608 before it reaches the new cache write at :3609. A previous /sessions search mapping remains armed and is then used at :3629-3646, although the latest numbered-list command showed no choices.
• _latest_gateway_session_choices is a plain unbounded dict at gateway/slash_commands.py:108-112. Main caps analogous long-lived session-source state at gateway/run.py:2975-2981 and trims it at :10863-10868.

Suggested changes

• Clear the remembered entry before each empty-list return and add the bare-/resume stale-selection regression case.
• Bound remembered session-key entries with an LRU or existing lifecycle cleanup, with coverage for eviction.

Automated hermes-sweeper review.

Clear stale numbered choices after an empty bare /resume, and bound remembered session keys.

Addressed in 8212691. Empty resume listings now disarm earlier search choices, and the mapping is a capped 512-entry LRU with eviction coverage. The focused resume suite passes: 58 passed.

The implementation, test slices, e2e, lint, type, docs, JS/TS, supply-chain, and Docker checks all pass. The only failing gate is Python lints / CI-sensitive file review, which requires a maintainer to apply the ci-reviewed label.

[GodsBoy]

Current head merges cleanly with current main. The implementation, tests, lint, type, docs, supply-chain, and Docker checks pass; the only remaining required gate is the maintainer-controlled ci-reviewed label. @teknium1, please check, apply the label, and merge if you are happy with it.
