Show named argument parameters throughout the UI:

- BytecodeView labels show "invoke add(a, b)" instead of
  "invoke add" when argument names are available in the
  invoke context's pointer group entries
- Call stack breadcrumbs show "add(a, b)" instead of "add()"
  in both programs-react CallStackDisplay and web TraceDrawer
- CallInfoPanel banner shows "Calling add(a, b)"

Add click-to-source for context badges:

- BytecodeView accepts onDeclarationClick callback
- Clicking an invoke/return/revert badge with a declaration
  field fires the callback with sourceId, offset, and length
- Falls back to pinning the tooltip if no declaration

Extract declaration and argument names from contexts:

- summarizeContext now returns argumentNames and declaration
- New formatCallSignature utility for consistent formatting
- New DeclarationRange type for click-to-source data
- CallFrame and CallInfo types carry argumentNames
