chore(release): cut v0.23.0

[bdchatham]

Cuts sei-agent-driver v0.23.0:

• A run that ends with no verdict deletes its session, so a re-run starts fresh instead of repeating the refused reply (fix(sei-agent-driver): delete the session of a turn whose reply was refused #467).
• SEIDROID_EFFORT sets the review's reasoning effort per session. A session create the server refuses with a 400 now exits 2 (ExitConfig) instead of 6 (feat(sei-agent-driver): set the review's reasoning effort per session #468).

Merging this triggers the Releaser (uci-release-publish.yml): the GitHub release, goreleaser, and the sei-agent-driver/v0.23.0 module tag that go install resolves.

Next: sei-protocol/uci bumps seidroid-review.yml's driver-version default and its pinned sha256 to v0.23.0. With sei-protocol/uci#118, the review then runs at high effort.

PR Summary

Low Risk
Single-file version bump with no runtime code changes in the diff; release automation runs on merge.

Overview
Bumps version.json from v0.22.0 to v0.23.0, marking the release cut for sei-agent-driver.

Merging this should trigger uci-release-publish.yml (it watches version.json), publishing the GitHub release, goreleaser artifacts, and the sei-agent-driver/v0.23.0 Go module tag. The release notes describe behavior shipped in this tag (e.g. session cleanup when a run has no verdict, SEIDROID_EFFORT, and config-refusal exit code 2); this PR diff itself is only the version stamp.
