程序员阿江(Relakkes) 6ae98a2f4e fix(desktop): align H5 mobile composer and diff scrolling
H5 exposes the desktop chat surfaces in a much narrower viewport, so the empty-session composer needs the same inset treatment as active sessions and generated diff rows need intrinsic width instead of compressing long code into the phone viewport.

Constraint: Keep desktop layout and short diff-row backgrounds unchanged while enabling sideways scrolling on H5.
Rejected: Force wrapping long diff lines | it makes code harder to inspect and diverges from desktop diff behavior.
Confidence: high
Scope-risk: narrow
Directive: Keep workspace diff rows content-width driven when adjusting mobile code preview styling.
Tested: cd desktop && bun run test -- src/pages/EmptySession.test.tsx --run
Tested: cd desktop && bun run test -- src/components/workspace/WorkspacePanel.test.tsx --run
Tested: cd desktop && bun run lint
Not-tested: Full bun run verify gate; change is scoped to desktop UI styling and covered by narrow Vitest plus typecheck.
