MiniClarc 2.6.2

v2.6.1 audit fixes

This release fixes verified regressions from the v2.6.1 audit.

Removed the phase LLM summary pipeline that could keep work alive after chat/window transitions and cause unwanted extra windows or background activity.
Added a duplicate project-window guard so opening the same project window focuses the existing window instead of creating another one.
Replaced the silent 200-turn display cap with explicit Show earlier turns / Hide earlier turns controls.
Fixed focus mode filtering for compacted original messages.
Added visible error handling for manual context compact failures.
Reset project-window state when a project window closes.
Stabilized orphan turn identity and fixed phase comparison edge cases.
Fixed JSONPath parsing and lookup regressions.
