docs: re-derive the three scaffolded-project transcripts after the description drop (#9342)

[os-steve]

Fixes#9342

#9263 (merged via PR #9335) makes create-objectstackdrop the blank template's own manifest.description at scaffold time. Three docs pages still quoted that line inside a scaffolded-project transcript, so all three had gone stale together.

Both printers guard on presence (packages/cli/src/commands/validate.ts:294, packages/cli/src/commands/info.ts:64), so the row does not become empty or undefined — it disappears entirely. Confirmed in my own runs, not inherited.

Re-derived from real runs — not hand-edited

CLI and scaffolder built at origin/main (b2d9e04d1); both fixtures scaffolded from the blank template with the built create-objectstack.

Fixture A — Support Desk (os validate). Scaffolded support-desk, then applied build-with-claude-code.mdx's own listings: the ticket object, the resolve action, the ticket views and the Support app, wired through the src/objects/index.ts barrel and the actions: / views: / apps: arrays exactly as the page's prose describes.

 ✓ Validation passed (180ms)
Support Desk v0.1.0
Data: 2 Objects 6 Fields
UI: 1 Apps 1 Views 1 Actions
Runtime: 3 plugins

Fixture B — my-app (os info). A different command surface, which is why this page could not be fixed from #9263's one-page framing. Scaffolded my-app, added the ticket object, one view and one action (no app), reproducing 1 Views 1 Actions and both object rows verbatim.

Verified mechanically, not by eye. Each edited block was diffed line by line against its run after normalising the config path and the timings. All three match; the only residual difference is Loaded in 59ms vs 88ms on cli.mdx. Timings and the sanitised /path/to/... are machine identity, not fixture identity, and are left as #9151 / #9262 left them.

#9152's work does reconstruct

The Support Desk fixture was built only from build-with-claude-code.mdx's own listings, and it reproduces every documented row — 2 Objects 6 Fields, 1 Apps 1 Views 1 Actions, 3 plugins, and Running author-time rules (41). The self-reconstructibility PR #9262 established is intact; no regression to report there.

Scope

Three line deletions, nothing else. Deliberately untouched:

• cli.mdx's Data migrations section — its row is docs: os migrate duplicates needs its row in the data-migration table, and the #8686 backfill guidance owes it the cross-reference the ruling asked for #9382's work, already verified on that card.
• cli.mdx's os compile block — re-derived by docs: two sample transcripts still print the pre-#4409 per-concern step list that the author-time rule registry collapsed into one line #9092 / PR docs: re-derive the os compile / os validate transcripts from real runs #9151.
• cli.mdx:1461's manifest-configuration example, which still shows a description: key. That is a hand-authored config, not a scaffolded-project transcript, and description remains an authorable manifest field — only the scaffolder's carry-over went away.

The card's own acceptance check now holds: git grep -n "Minimal ObjectStack environment" -- content/docs/ returns no hits.

Gates

Union re-derived from the actual changed paths with node scripts/pm/dispatch-gates.mjs, run after the final commit, at e92291332 — all green:

check:nul-bytes · check:docs-audit-scope · check:docs-redirects · check:role-word · spec check:empty-state · spec check:liveness · spec check:strictness-ledger · spec check:variant-docs · check-cross-package-test-inputs

Plus a control-byte self-scan over the three changed files (no hits).

Docs-only, releases nothing — skip-changeset.
