Obscurax.Error exception (obscurax v0.1.0)

Structured error for all Obscurax operations.

All NIF operations return {:ok, result} or {:error, %Obscurax.Error{}}. Bang variants (goto!/2, etc.) raise this as an exception.

The context map carries operation-specific details that vary by kind:

kind	context fields
`:navigation`	`url`
`:timeout`	`url` or `selector` + `timeout_ms`
`:element_not_found`	`selector` and/or `node_id`
`:js_eval`	`expression`
`:no_page`	(empty)
`:page_closed`	(empty)
`:internal`	(empty)

All context keys are atoms. Fields not relevant to a given kind are nil.
