fix(desktop): reserve chat action hover space

Browse Source 
Message actions still fade in on hover and focus, but their row now keeps a stable height so transcript content does not jump when the pointer enters or leaves a message.

Constraint: Preserve the existing hover-only visibility and copy/fork interaction model.
Rejected: Keep animating height from zero | it causes the visible transcript reflow this change is fixing.
Confidence: high
Scope-risk: narrow
Tested: cd desktop && /Users/nanmi/.cache/codex-runtimes/codex-primary-runtime/dependencies/node/bin/node ./node_modules/typescript/bin/tsc --noEmit
Tested: git diff --check -- desktop/src/components/chat/MessageActionBar.tsx desktop/src/components/chat/MessageList.test.tsx
Not-tested: Focused Vitest could not complete in this local shell because the Vitest/esbuild startup process stalled or reported esbuild service stopped.
