Reviewer flagged that ToolExecutionComponent.isTranscriptBlockCommitStable\ntreated any block with a defined #result as commit-stable, so a long\nstreaming SSH partial render could sit on its stable pending header until\nderiveLiveCommitState's stable-prefix ratchet promoted it to native\nscrollback, then the final SSH glyph render would land below and strand a\nduplicate pending header above the settled frame.\n\n- Added ToolRenderer.provisionalPartialResult opt-in for renderers whose\n partial-result chrome differs from the final render.\n- Honored it in ToolExecutionComponent.isTranscriptBlockCommitStable so the\n block stays commit-unstable while isPartial holds and flips stable as soon\n as the result settles.\n- Set provisionalPartialResult: true on the SSH renderer.\n- Added test/tools/ssh-commit-stability.test.ts covering the partial/final\n transition and the non-regression for bash.\n\nFixes #3177
