chore(ui-tooling): drop two test-only scripts and six CLI aliases nothing runs (slice 2 of #25920) (#26024)

Part of #25920 — slice 2 of the unwired-tooling cleanup (slice 1 was
#26004). The card stays open for the slices listed at the end.

## Summary

Deletions only: 7 files, −1,322 lines, on `main` 88531fa.

- `ui/scripts/coverage-red-cause-census.mjs` +
`coverage-red-cause-suspects.json` + its test → **delete.** Its header
calls it "a ONE-OFF CENSUS, not a gate … nothing in CI calls it";
nothing but its test and one `markdown-test-inputs.mjs` row named it
(row removed).
- `ui/scripts/extract-mdx-demos.mjs` + its test → **delete.** A one-off
MDX-to-schema-catalog migration helper; no alias, no workflow; nothing
but its test and one `markdown-test-inputs.mjs` row named it (row
removed).
- `ui/package.json` aliases `cli`, `objectui`, `doctor`, `studio`,
`generate`, `g` → **delete.** All six point at
`packages/cli/dist/cli.js`; no workflow, script or document runs any of
them (exact `pnpm NAME` / `pnpm run NAME` grep over the whole tree: 0
hits; the `objectui:build` / `objectui:refresh` hits are different root
scripts).

Corrections to the #26004 body's "remaining slices" table, kept out of
this PR on purpose:

- `test:unit` and `test:integration` **stay**:
`ui/scripts/__tests__/package-scripts-vitest-projects.test.ts` pins both
against the vitest projects.
- `start` and `site:start` **stay**: both targets exist
(`@object-ui/console` `preview`, `@object-ui/site` `start`) and
`ui/apps/console/README.md` documents `pnpm start`.
- `check` **stays**: root `ci.yml` runs `pnpm --dir ui run check`.

Nothing is wired.

## Verification (head e1651b4)

- Exact-name `git grep` across the whole tree (AGENTS.md, skills,
.claude, docs, every manifest, CHANGELOGs excluded) for both scripts,
the ledger and the six aliases: no hits outside the deleted files and
the two removed rows. No governed text touched.
- ui suites that read the scripts inventory and manifest
(markdown-test-inputs, package-scripts-vitest-projects,
check-unreferenced-sources, ci-cd-pipeline-doc,
vitest-invocation-guard): 5 files, 200 tests passed. `pnpm --dir ui run
check:unreferenced-sources` exit 0, `check:test-path-roots` exit 0.
- `dispatch-gates --commands` derived families: see the report on the
card for the per-family exit codes.
- No changeset: private ui tooling and the private ui root manifest
only.

## Remaining slices

- One report-only census per PR: `tsconfig-test-parity-census` (430
lines plus ~10 pointer comments), `page-key-read-census` (1,146),
`dollar-dialect-alias-census` (1,109), `check-component-surface-parity`
(2,584), `changeset-polarity-census` (3,525, split in two to stay under
the 3,000-line human-merge threshold).
- Then the mechanical tsconfig dedupe.
- The eight gate-shaped scripts listed on #26004 stay for a maintainer
wire-or-delete ruling.
