Further Enhancements to the Debugger Extension

[mreinstein]

Changes

Features

• add a timeline panel that allows you to visit any step
• add live button to return to live mode, and clear to empty out the timeline history
• better icons for the vertical and horizontal dock buttons

Bugfixes

• make the breakpoint hyperscript work in the debugger pane when it's open
• fix the step back button (F9) to work
• fix a regression in the workers extension (missing several arguments to _hyperscript.apply and better url handling)
• add padding to the bottom of the page when debug pane is open so none of the body is obscured
• fix the workers test page to actually work with debugger

Refactor

• remove as many half-baked, buggy features as I could find
• remove the public ttd api and the url params
• expose a new hyperscript event, hyperscript:breakpoint which when cancelled falls back to built in javascript debugger
• move css to a separate file and use @scope so it won't pollute page scope and simplifies selectors
• update esbuild from 0.27 -> 0.28 for import with { type: 'text' } support
