fix: deduplicate idle sessions and refresh session data on transitions

Multiple claude processes in the same CWD share one sessionFile via
findActiveJsonl, causing duplicate idle entries. Now deduplicates by
project+sessionFile key. Also refreshes session data on busy→idle
transitions so the parser fix takes effect immediately.
