feat!: harden raw browser control and packaging

- Add safe-by-default policy gates for raw command surfaces: command, script, and serve-http /command.

- Require explicit opt-ins for page reads, browser control, and high-risk commands such as dom.eval, storage.*, and screenshots.

- Remove all cookies support from CLI, SDK, extension commands, permissions, constants, docs, and tests.

- Add diagnostic, events, watch, workspace, remote, raw command, script, HTTP gateway, tree-view, session import/export, and extension info/capability commands.

- Add Chrome Web Store packaging that strips manifest.key while keeping local packages with a stable native-messaging extension ID.

- Bump browser-cli and extension version to 0.14.1 and cover the new behavior with pytest and extension packaging tests.

BREAKING CHANGE: cookies commands and the b.cookies SDK namespace have been removed; generic raw command execution now blocks non-safe commands unless explicitly allowed.
