- Standardized elision markers across all tool outputs and filters to use cohesive `[...N [type] elided...]`, `[...Nln elided...]`, and `[...xB elided...]` syntax. - Updated documentation, prompts, and test expectations to reflect the unified elision format. - Improved transcript viewer robustness by preventing content aliasing through path-inclusive signature hashing. - Added logic to clear stale transcript content when associated session files are deleted, accompanied by verifying test cases.
