refactor(telemetry): add standalone telemetry for create-sanity

[mttdnt]

Description

Reapply of #892 on top of #1011. Adds real telemetry to create-sanity so we get the same usage/error data as the oclif CLI, without pulling in oclif as a dependency.

• Replace noop telemetry store with setupStandaloneTelemetry — mirrors the oclif prerun hook without the oclif dependency, flushes inline with a 3s timeout instead of a detached worker
• Add telemetryDisclosureStandalone and unify telemetryDisclosure to re-export it
• Parse args before telemetry setup so --help exits without showing the disclosure banner (parity with oclif where --help runs before the prerun hook)
• output.error throws InitError so errors flush through the same catch path
• Delete noopTelemetry.ts

What to review

• packages/@sanity/cli/src/util/telemetry/setupStandaloneTelemetry.ts — standalone telemetry setup
• packages/@sanity/cli/src/actions/telemetry/telemetryDisclosureStandalone.ts — oclif-free disclosure
• packages/create-sanity/src/index.ts — restructured to parse args first, then setup telemetry
• packages/create-sanity/src/version.ts — version info for telemetry

Testing

• New tests for setupStandaloneTelemetry and telemetryDisclosureStandalone
• TypeScript type checking passes
• All changed-file tests pass

Missing changeset

No changeset is present in this PR's diff. The previous pr-892.md changeset (removed in db2f242) had:

'@sanity/cli': minor
'create-sanity': minor

add standalone telemetry for `create-sanity`

The bump type (minor) and summary were appropriate. The squiggler bot auto-created and then removed a replacement (pr-1018.md) in a later commit. If this PR targets main as part of the stack merge, the changeset needs to be present — confirm whether it's expected to land with the parent (#1011) or needs to be re-added here. Fix this →

Everything else looks good — logic, test coverage, and implementation are clean.
