addedSample test case and constraint parsers for contest (/contest/*) and gym (/gym/*) paths.

improvedEditor integration protocol fetches fresh test cases asynchronously on trigger events.

improvedAsynchronous state saving preserves timer integrity across service worker sleep transitions.

improvedRefactored idle detection threshold to a generous 15 minutes, accommodating non-keyboard design cycles.

improvedContext menu registrations restricted to supported URL formats to optimize resource footprint.

fixedResolved race conditions in contest and gym URL parsing routines.

addedDaily time breakdown bar chart using Chart.js inside the extension popup container.

addedProblem-by-problem historical ledger sorting entries by relative recency.

addedstreak count calculator and consistency score aggregator.

improvedRedesigned popup layout for enhanced text scanning and responsive boundaries.

improvedExpanded LeetCode problem sheet DOM parser compatibility.

improvedRe-entry loops in background worker restore session metrics gracefully after browser restarts.
