* fix: show steer/queue submenu during question carousel when text is typed
- Cancel button now hides when input has text during question carousel
(matches behavior during regular in-progress requests)
- Queue/steer submenu now appears during question carousel and tool
confirmation states, since requestInProgress is false in those states
- Removed unused requestInProgressWithoutInput and pendingToolCall vars
- Replaced hardcoded box-shadow values with new CSS variables for consistency and improved theming.
- Updated styles in postEditWidget, findOptionsWidget, findWidget, floatingMenu, hover, parameterHints, peekViewWidget, renameWidget, stickyScroll, suggest, actionWidget, hover, quickInput, agentFeedback components, and more.
- Introduced new shadow variables: --vscode-shadow-sm, --vscode-shadow-md, --vscode-shadow-lg, --vscode-shadow-xl, and --vscode-shadow-hover for better control over shadow effects.
