feat(engine): DOM + AbortSignal + storage fixes surfaced by WPT conformance work (#219)
Engine-only changes pulled out of the WPT conformance branch. The tests, runner, and harness vendoring that drove these have moved to a separate benchmark repo (obscura-bench). Real bug fixes: - Tree::insert_before created a self-cycle when the inserted node was its own reference (the spec-conformant `child.after(x)` path that the testharness's ChildNode helpers exercise). The fixup wrote node.prev_sibling = node.next_sibling = own id; every subsequent childNodes / querySelectorAll walk then looped forever and obscura burned RAM until OOM. Per spec the op is a no-op; we now early-return. - Tree::text_content extended to return own data for direct CharacterData access (Text / Comment / ProcessingInstruction). - Element.namespaceURI now reflects the namespace passed to createElementNS instead of collapsing every non-svg namespace to xhtml. Without this, code that creates elements in MathML, custom XML namespaces, or the empty namespace gets misclassified as HTML. - AbortController / AbortSignal: the previous shim was a plain object whose addEventListener was a no-op, so listeners for 'abort' silently never fired and any AbortSignal.timeout / AbortSignal.any chains broke. New impl tracks aborted/reason, has a real addEventListener / removeEventListener / dispatchEvent surface, honors `once`, and implements the static abort / timeout / any factories crawlers use for budgeted fetches. - StorageEvent class added. localStorage / sessionStorage mutations now dispatch 'storage' events on the parent window and every iframe window so cross-frame onstorage listeners fire. - ProcessingInstruction (nodeType 7) and DocumentType (nodeType 10) constructors plus document.createProcessingInstruction and document.implementation.createDocumentType. textContent returns null for Document and DocumentType per spec. - insertAdjacentText / insertAdjacentElement on Element. Without these the testharness output renderer threw in a forEach without try/catch, breaking the completion callback chain for every test with subtests. - Window + Node addEventListener filter non-callable listeners, accept the EventListenerObject shape (object with handleEvent), dedupe by (type, callback, capture), honor the `once` option, and snapshot the listener list before dispatch so a `once: true` removal mid-iteration doesn't corrupt the loop. - Iframe HTML loader now extracts head <script> blocks and body on-handler attributes (`<body onstorage=...>`), evals scripts in the parent realm after the iframe window is built, re-attaches handlers as window listeners. Same iframe element reusing its src no longer double-registers in the iframe registry. - ops.rs validate_fetch_url honors the OBSCURA_ALLOW_PRIVATE_NETWORK env var, and the CLI --allow-private-network flag mirrors itself into that env so the js-side fetch gate matches the http_client gate. Without this, iframe loads of 127.0.0.1 resources were blocked even with the flag set. - ops.rs: create_processing_instruction, create_doctype, pi_target, doctype_name, doctype_public_id ops added; set_text_content extended to handle PI nodes.
