### Fixes

- CLI/migrate: humanize Codex conflict-status messaging across the migrate UI so selection prompts and plan/result rows say "Codex skill already installed in workspace" instead of surfacing internal `MIGRATION_REASON_*` codes. Thanks @sjf.

- CLI/migrate: render migrate result rows with distinct glyphs for manual-review (🔍) and archive (📖) items instead of the misleading "skipped" and "migrated" checkmarks, so users can see which entries still need attention versus which were filed away. Thanks @sjf.

- CLI/migrate: split Codex migrate output into separate preview and result phases so the Before plan and After result render through clack with independently tunable copy. Thanks @sjf.

- Codex app-server: project bundle and user MCP servers into Codex threads, rotate threads when an MCP server is disabled, scope bundle MCP injection to bundled servers, and resend user MCP config on resume so MCP changes take effect mid-session without restarting the agent. (#81551) Thanks @jalehman.

- Codex migration: invoke the managed Codex binary instead of a stale system `codex` for source-config migration plans, so users running the bundled Codex runtime get plan output that matches the binary the gateway will actually use. (#81582) Thanks @fuller-stack-dev.

- Subagents/maintenance: preserve pending subagent registry sessions during session-store cleanup, pruning, and disk-budget enforcement so in-flight subagent runs are not deleted by background maintenance before they complete. (#81498) Thanks @ai-hpc.
