Kiro IDE: Memory Across Chat Sessions

This release brings Memory to every Kiro IDE user. It also makes find more reliable in long Markdown Review documents, fixes a sign-in screen that ignored Cancel, and fixes Kiro failing to start after a `.deb` install on Ubuntu 24.04.

[Carry useful context across sessions with Memory] Memory lets Kiro carry useful context such as repository conventions, corrections, and approaches already ruled out from one session to the next. Select the Memories icon in the activity bar to open the Memory view and review what Kiro remembers. Chat shows when Kiro accesses or changes a memory. Choose how Kiro uses and learns from memories in the Kiro Agent: Memory setting, including Use only, which lets Kiro use memories without changing them. Learn more ->

[Improvements] More reliable find in Markdown Review: Find now keeps your current match when the document refreshes, ignores hidden math text and diagram controls, and handles documents with many matches. Comments stay anchored to their passages across refreshes

[Fixes] Fixed the "We will take you to your default web browser to sign in" screen ignoring Cancel when sign-in never completes. Cancel now returns you to the sign-in start, and a cancelled attempt no longer interrupts a retry

[Fixes] Fixed Kiro not starting after installation from the `.deb` package on Ubuntu 24.04 and later Ubuntu versions
