HermesCLI._display_resumed_history() calls the module-level _strip_reasoning_tags() to clean assistant content before rendering the recap panel. The tag list was missing <thought> (Gemma 4) and there was no pass for stray orphan </tag> closes, so those variants leaked internal reasoning into the recap display (#11316).
- Add <thought> to _REASONING_TAGS.
- Add a third regex pass that strips orphan close tags (e.g. 'stuff</think>answer' → 'stuffanswer').
- Apply IGNORECASE to closed-pair and unclosed-pair passes so mixed-case variants (<THINK>, <Thinking>) are handled uniformly — previously both 'THINKING' and 'thinking' had to be listed explicitly as distinct tuple entries, which missed <Thinking>.
7 new regression tests in tests/cli/test_resume_display.py covering: <think>, <thinking>, <reasoning>, <thought>, unclosed <think>, multiple interleaved blocks, and orphan </think> close.
Resolves#11316.
