Agent-browser 0.43 drops Node wrapper

Startup latency is the silent killer of agent tool loops, and shedding Node overhead makes agent-browser feel like a native OS primitive rather than a heavy automation layer.

• –A 2 ms startup time eliminates cold-start penalties when autonomous coding agents trigger one-off browser actions in bash subshells
• –Distributing platform-specific native binaries across npm, bun, pnpm, and yarn cuts download footprint up to 7.5x without requiring Rust toolchains
• –Single-pass accessibility tree parsing dramatically accelerates ref extraction on bloated, script-heavy web applications
• –New snapshot hints for nameless DOM elements solve disambiguation failures that previously broke LLM navigation loops
• –Direct native binary execution widens the performance gap between agent-browser and heavyweight browser drivers
