Subject: [PATCH] fix(dev): skip redundant deploy when TUI deploy already
 succeeded
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The TUI deploy flow (useDeployFlow) wrote deployed state but never
stored the deployHash. When `agentcore dev` subsequently called
canSkipDeploy, the stored hash was undefined — causing it to always
redeploy even with no changes.

Constraint: computeProjectDeployHash must use the same ConfigIO as the deploy flow
Rejected: Move hash storage into buildDeployedState | would change the shared utility's contract and require all callers to pass configIO
Confidence: high
Scope-risk: narrow
