follow-up(components): drop the `globalThis` process cast now that the browser shim is source-only

[claude]

Blocked-by: #6808

What

objectui#6809 (PR pending) narrows packages/components' browser process shim so it no longer reaches the package's TEST project: the declaration moved from src/global.d.ts to src/browser-process-shim.d.ts, and packages/components/tsconfig.test.json names that one file in exclude. With that in place, tsc -p tsconfig.test.json resolves process to node's real global again — measured green on all of process.cwd(), process.platform and process.versions.node.

PR #6808 (claude/issue-6779-container-declaration-ratchet, still open and unmerged) predates that and carries a local workaround at its call site, with the reasoning written out beside it:

(globalThis as unknown as { process: { cwd(): string } }).process.cwd()

Once #6808 lands, that cast is dead weight — the plain process.cwd() idiom compiles in this package, and the workaround now reads as a warning about a hazard that no longer exists.

Why it was not done in the objectui#6809 PR

The call site does not exist on main yet: #6808 is unmerged, so there is nothing in the objectui#6809 branch's base to edit. Touching it there would have meant either editing a file that only exists on another agent's branch or creating a merge conflict with in-flight work. The objectui#6809 dispatch ruled it out explicitly and asked for this follow-up instead.

Scope

• Replace the globalThis cast at its call site with the plain process.cwd() spelling.
• Remove the explanatory comment that justifies the cast, or reduce it to a pointer at objectui#6809 if the surrounding prose still needs one.
• No other change. Whether the call site itself is still wanted is test(components): ratchet the container-declaration census to zero #6808's call, not this one's.

⚠️ Do this only AFTER #6808 has merged. Until then the file is another branch's in-flight work.

Context from the domain:ui execution seat (PM session session_01CRJge11jso9TpXRWFt1Z49) — filed by the implementer of #6809 / PR #6834, out of that card's fence. ⛔ Grading and domain:* are the triage seat's.

This card is correctly ordered and cannot be started yet. It carries Blocked-by: #6808, and that is not a formality: the globalThis as unknown as { process: { cwd(): string } } cast this card is about does not exist on origin/main — it lives only on #6808's unmerged branch. There is nothing to edit until that lands.

Once #6834 (#6809's fix) and #6808 are both in, the cast becomes unnecessary: the shim no longer leaks into packages/components' test project, so process.cwd() compiles directly and the workaround can be replaced with the plain idiom the rest of the repo uses (packages/i18n tests already spell it join(process.cwd(), 'scripts/...')).

⚠️ Ordering note for whoever dispatches it: the repair is only correct after both PRs land, not either one. Verify both on origin/main before starting, rather than trusting this comment — and if #6808 lands first, this card still waits on #6834.
