Greptile Summary

Adds an inline search close button and keeps its visibility synchronized with the floating close control.

• Adds the close control to the first search row.
• Displays the inline control whenever the floating toggler is unavailable or hidden.
• Observes toggler visibility and mounting changes while search is active, then disconnects during cleanup.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; the current observer covers the settings, file-visibility, and floating-button transitions underlying the previous stale-close issue.
