feat: add cursor-interactive element detection in snapshots (#374)

* fix: only warn about ignored flags when explicitly passed via CLI

The warning about launch-time options being ignored (when daemon is
already running) was incorrectly shown when options were set via
environment variables like AGENT_BROWSER_EXECUTABLE_PATH, even when
no CLI flag was passed.

Now the warning only appears when flags are explicitly passed on the
command line, not when values come solely from environment variables.

Fixes #372

* feat: add cursor-interactive element detection in snapshots

Add -C/--cursor flag to snapshot command that detects clickable elements
that don't have proper ARIA roles but are interactive based on:
- cursor: pointer CSS style
- onclick attribute/handler
- tabindex attribute

This helps with modern web apps that use custom divs/spans as buttons.

Fixes #366
