Dev Browser adds scriptable browser layer

Hot take: this is more useful as an agent control surface than as a generic browser bot, because it keeps the interaction model scriptable and stateful instead of hiding everything behind screenshots.

• –The core pitch is Claude-native browser automation with a skill/plugin path, not a separate app the model has to fight.
• –Persistent pages and a full Playwright API make it better suited to multi-step workflows than one-off clicks.
• –The release itself is incremental, but the underlying product positioning is clear: reduce brittleness and token waste versus heavier browser control setups.
• –The "lighter-weight way to drive web pages" framing is credible if you already want Claude to write and run scripts rather than steer a GUI.
