fix(search): scope deprecated_by filter to user tables only

[Kendrick-Song]

Summary

compile_filters() unconditionally appended deprecated_by IS NULL to every LanceDB query, but the deprecated_by column only exists on user-scoped tables (episode, atomic_fact — Reflection V1). Agent tables (agent_case, agent_skill) lack this column, causing a SQL error on agent search/get queries.

Fix: gate the clause behind owner_type == "user" so agent queries no longer reference a non-existent column.

Also bumps version to 1.1.2.

Checklist

• I kept the change scoped to the relevant area.
• I am opening this from a separate branch, not pushing directly to main.
• I updated docs, examples, or setup notes when behavior changed.
• I added or updated tests when the change affects behavior.
• I did not commit secrets, .env files, dependency folders, or generated output.
• Active relative links in Markdown files resolve.

Notes for Reviewers

• The exclude_deprecated parameter was already removed from the public API in v1.1.1 (15efd11), but the unconditional deprecated_by IS NULL clause remained in compile_filters(). This PR completes that cleanup.
• docs/openapi.json regenerated via make openapi to match the 1.1.2 version bump.
