chore: sync isanagent main

[efecnc]

Updates the recorded İsanAgent main revision in Cargo.lock. ALTAI already refreshes İsanAgent before compile (pnpm isanagent:sync / CI / release), so this PR only keeps the lockfile tip current.

Merged automatically by Sync İsanAgent only after every CI check has passed.

Sync İsanAgent — CI failed

Leaving this PR open for manual triage. Recent checks:

[amazon-q-developer]

This PR updates the Cargo.lock file to sync the isanagent dependency from commit ea90fa0 to 7018685. The changes include routine dependency version updates for several transitive dependencies (colored, iana-time-zone, shellexpand, winapi-util). These are automated lock file updates that track the exact versions of all dependencies in the build. No issues found that would block merging.

You can now have the agent implement changes and create commits directly on your pull request's source branch. Simply comment with /q followed by your request in natural language to ask the agent to make changes.

Closing in favor of #232, which bumps IsanAgent to the same ACP tip (7018685) and fixes the HostConfig / altai acp surface so smoke builds succeed.
