fix(browser): wire all hanzo.* commands end-to-end, zero gaps

- Forward hanzo.dblclick/hover/type/clear/select/check/uncheck through
  chrome.runtime to browser-control
- Add browser.dblclick, browser.clear, browser.check, browser.uncheck,
  browser.focus, browser.blur, browser.drag, browser.scrollIntoView
  to handleBrowserAction
- Add actionMap for naming mismatches (url→getURL, title→getTitle, etc.)
- Verified: 0 gaps in server→client→browser-control chain
