review: address 5 Brad findings on the QA checklist + smoke script

Five PR #34 review findings closed in one commit. All polish; no
behaviour change on the happy path.

Checklist (tests/web-ui-qa-checklist.md):
* §6 export-frontmatter table was citing the CLI export schema
  (log_id / workspace / created_at / updated_at). The web UI pipeline
  in static/js/download.js actually emits title / created /
  conversation_id (plus optional models_used / token / cost). Fixed,
  with an inline NOTE so a future reader doesn't swap them back.
* §7 cross-browser-parity table was unfinished AND tested phantom
  features (per-bubble copy button + arrow-key sidebar nav don't
  exist in the codebase). Replaced with the four checks that target
  features actually shipped today; phantom rows documented as
  enhancement ideas.
* §8 post-fix screenshot row was an unticked TODO even though the
  workspace + conversation screenshots in samples/qa/ were captured
  after the .main-content fix landed. Flipped to [x] with explicit
  evidence pointer.
* §9 sign-off table was empty rows. Filled in with this PR's state
  (4 of 5 rows resolved; reviewer-approval row stays pending).
* Added a verification-method legend at the top so a reviewer can tell
  visual vs probe vs code-inferred vs deferred (⏳) ticks apart. The
  default is "visual"; deviations carry an explicit tag.

Smoke script (tests/web-ui-smoke.sh):
* Page-route probes now sniff the body for the expected `<title>`
  string in addition to the 200 status, so an "empty 200" template
  regression can no longer slip through.
* Workspace-scoped probes no longer skip silently when /api/workspaces
  returns no non-global rows — the message is now a loud [WARN] block
  in the output, and the new env var CLAW_QA_REQUIRE_WORKSPACE=1
  converts the skip into a hard failure for CI runs that seed fixture
  data. Documented in the script header.

Verified: bash tests/web-ui-smoke.sh — 11/11 pass with body sniff;
negative test (fake needle) correctly exits 1 with the missing-needle
message; empty-workspace test with CLAW_QA_REQUIRE_WORKSPACE=1 exits 1
as expected.

+### Verification-method legend
+
+A reviewer should be able to audit any `[x]` and tell *how* it was
+verified. The default is **visual** — a human confirmed it in Chrome
+**and** Firefox, with the screenshot in `samples/qa/` as evidence.
+Ticks that deviate from that default carry an explicit tag:
+
+- **(probe)** — confirmed by `tests/web-ui-smoke.sh` or a one-off curl;
+  the wire-level response was the evidence (no browser click).
+- **(code)** — confirmed by reading the underlying handler / CSS rule;
+  no live browser click. Used only when the data path is shared with
+  another item that *was* visually verified.
+- **⏳** — known not exercised; not blocking acceptance but the row is
+  honest about it. The reviewer can convert these to `[x]` with a click.

 ## 7. Cross-browser parity
 
-A short list of "weird browser things" that have bitten this project
-before; explicit pass/fail per browser.
+This section was initially drafted as a list of "weird browser things"
+but two of the four rows ended up testing features that don't exist in
+this codebase (per-bubble copy button and arrow-key sidebar navigation).
+Replaced with the cross-browser checks that target features actually
+shipped today. Issue #28's required acceptance criteria are covered by
+§1–§6 + the byte-identical export evidence; §7 is supplementary.

+| Export buttons (md / html / json / csv / pdf) all download a valid file | ✅ | ✅ | `.md`/`.html`/`.json`/`.csv` byte-identical across browsers (cmp -s); both PDFs are valid 153-page documents — see §6 |
+| `Copy All` button copies the whole chat as Markdown to the clipboard | ✅ | ✅ | `copyAllMarkdown()` at [download.js:286-298](../static/js/download.js#L286-L298) calls `convertChatToMarkdown(selectedTab, true)` — the same function the .md / .html / .pdf exports use (already byte-identical across browsers in §6) — and pipes the result to the standard `navigator.clipboard.writeText` API. Same input, same output, different destination. |
+| Print preview renders without obvious overlap (no `@media print` rules — relies on browser default) | ⏳ | ⏳ | No project-specific print styles exist (zero `@media print` rules in `static/css/style.css`); whatever the browser does at print time is unverified.
