ci: reject unused SSH exports with Knip

[juliusmarminge]

SSH's unused exports are now cleaned up in the preceding layer. Add packages/ssh to the existing Knip export check so CI rejects new unused SSH exports and types.

The existing files/dependencies check and other workspace checks stay enabled. No dependencies, suppressions, or entry-point exceptions are added.

Verification: vp run knip:check passes with SSH included. The preceding layer resolves the 17 SSH findings that would otherwise fail this gate. No runtime or UI changes.

Model: gpt-6 astra. Harness: Codex in T3 Code.

Note

Add packages/ssh to knip:check workspace list

Extends the Knip export analysis to cover the packages/ssh workspace so unused SSH exports are caught in CI.

Approvability

Verdict: Approved at 2cf0792

Macroscope's review found this PR approvable — This is a small CI-only change that extends the existing Knip export check to the SSH workspace, with no product runtime, default, schema, or deployment impact. It broadens static-analysis coverage rather than suppressing diagnostics.

Notes:

• No code objects were reviewed. Approvability was decided on eligibility alone.
