Daniel Han 69ef56edb3 Studio: tighten re-prompt artifact guard for non-alpha fences, planning lists, incomplete HTML
Addresses three follow-ups flagged on the first cut of this PR by static
reviewers and parallel reviewer runs:

1. Numbered plan-only stalls were treated as completed answers. A
   response like `Here's my plan:\n1. Search the web\n2. Summarise`
   matched both `_INTENT_SIGNAL` and the numbered-list branch of
   `_HAS_ANSWER_ARTIFACT`, so the tool-forcing re-prompt was skipped.
   That contradicted the PR's stated invariant that plan-only stalls
   still re-prompt. The list now has to be paired with no plan framing
   (no `Here's my plan` / `plan:` / `approach:`, no intent phrase
   followed by a tool-action verb) to count as an artifact.

2. Closed code fences with non-alpha info strings (`python3`, `c++`,
   `c#`, `objective-c`, `ts-node`, `bash-session`, `python linenums="1"`)
   were not recognised by the `[a-zA-Z]*` info-string class. Complete
   answers in those languages still re-prompted and could be wiped.
   The info-string class is now `[^\r\n]{0,200}` and the closing fence
   may be indented.

3. Bare `<!doctype` or `<html` text was treated as an artifact. A
   plan-only response that mentions `<html>` in prose now no longer
   bypasses the re-prompt; the HTML branch requires a closing
   `</html>` (doctype prefix optional).

All `[\s\S]{...}?` runs are length-bounded so ReDoS-style adversarial
input stays linear. ReDoS guard tests cover CRLF spam and repeated
`<html ` openings without close.
