Runtime recapture for [#31925](https://git.cafe/pingdotgg/t3code/pull/31925).

Captured 26/26 requested rows per side (52/52 before/after row captures): R1–R22 and R24–R27. Each side also includes R19/R20/R21 recovery and R25 execution-count follow-ups, for 30 evaluate calls per side. Unverified rows: none. R23 was not requested.

Environment: Linux x64; Node v26.13.0; playwright-core 1.60.0; headless Chromium 148.0.7778.96. Limits: 1,000 ms for R10, R11, R15, R19, R21 and the R19/R21 recovery calls; 5,000 ms elsewhere. Same driver, one complete run per revision. Each independent row uses a fresh context/page/CDP session; follow-ups retain the preceding session. Synthetic page `http://preview.test/start` is intercepted locally with `<title>p</title>`.

Layer: actual production `ServerBrowserPage.evaluate` export from each detached checkout, against headless Chromium. No T3 server, live data, MCP envelope, Electron runtime, or render path is exercised. All browser contexts and browser processes were closed.

What else changed:
- None observed among R1–R22 versus the earlier after transcripts: R1–R18 labels/results match the PR-body capture, and R19–R22 including recoveries match the prior supplemental capture. Error tags are displayed explicitly here.
- Newly captured R24: before reports `SyntaxError: Unexpected reserved word`; after retries in REPL mode and returns `3`.
- Newly captured R25: both sides report the runtime SyntaxError, issue exactly one `Runtime.evaluate` for the failing expression, and then return execution count `1`. The first exception includes `stackTrace`, so after does not retry it.
- Newly captured R26: both sides report `SyntaxError: Unexpected token ';'`; after performs one REPL retry of the parse failure.
- Newly captured R27: both sides return `5`, with one classic evaluation.

R1–R18 retain the original PR row labels. R19–R22 retain the supplemental driver's exact inputs (`Error("x")`, `while(true){}`, and 70,000 characters for R22); R22 serializes to 70,002 bytes against the 64,000-byte helper cap. Every expression, option, full error, and CDP request/response is in the structured raw captures. R24 uses `var s = 0; for await (const x of (async function*(){ yield 1; yield 2 })()) s += x; s`. R25 uses `window.runs = (window.runs ?? 0) + 1; new Function('await 0')`, followed by `window.runs`. R26 uses `x = ; await 1`; R27 uses `"await".length`.
