Rip out the dead isolated-preview mode and the private repo's job

Comparing this branch's live against main's turned up two whole features that
never made sense here. -2,466 lines.

1. The isolated source-artifact preview was never switched on.

`scaffoldSourceArtifactSession` is only reachable via live-wrap's `--isolated`,
and nothing passes it: not the server's preflight, not live.md, nothing. Proved
it end-to-end — the default wrap writes markers straight into real source and
creates no previews/ session. So the mode was wired through three modules,
carried its own accept/discard branches, browser branches, server metadata
resolution, preview-mode classifier entry, and test suites, and none of it could
run.

Worse, live.md documented it as the active path and told the agent "The true
source is only the publisher's hash fence and must remain byte-identical until
Accept." That is false: the wrapper lands in source at scaffold time and each
revision rewrites it. An agent following that sentence believes source is
protected when it isn't, and the leftover artifacts are what made accept resolve
the wrong file in the first real run. live.md now describes what actually
happens, including that markers are visible in source until Accept or Discard.

Removed: source-artifact.mjs, --isolated, the preflight's isolated option, the
accept/discard branches, four dead browser branches, the server's previews/
resolution, the classifier entry, and their tests. Kept the previews/ gitignore
pattern: an ignore line for a directory that cannot exist is free, and a test
pins it.

2. Quality judging belongs to the private evals repo, which says so.

runner/live/README.md there is explicit: the public repo owns protocol
correctness, framework coverage, timing, source commit, recovery, and a
rubric-free evidence bundle; the private repo owns the task corpus, baselines,
comparative judges, and release-quality decisions — "Do not add quality rubrics,
competitor comparisons, or broad fixture corpora to the public Live benchmark."

This branch added exactly those: an LLM judge scoring 1-10 on "off-brand,
generic-AI" (live-rendered-quality.mjs, judge-live-rendered.mjs), a
cross-provider comparison with a BRAND_CONTRACT rubric (live-provider-benchmark
.mjs, benchmark-live-providers.mjs), and a brand-fidelity fixture corpus. All
removed, with bench:live:providers and their suite entries.

Also removed tests/framework-fixtures/README.md's "External quality-eval
fixtures" section: it documented a bench:live workflow using --fixture-dir,
--agent=codex, --action and --evidence-bundle, none of which benchmark-live.mjs
implements, plus an evidenceCapture block nothing reads.

Kept: timing benchmarks (the public repo's half of that boundary), progressive
publication, the source lock, poll lanes, and Nuxt/Vue component previews.

Coverage note: deleting the isolated suites took the only tests for
`source_locked` classification with them, so the plain wrapper path — now the
only non-component preview — gets equivalent accept and discard coverage. Both
new tests fail if mode:'error' is removed.

Prepared with AI assistance under maintainer direction.
