* fix(agents): align Codex model catalog and reasoning efforts with Codex CLI 0.144
- Remove gpt-5.3-codex from the Codex model picker: saved picks of it are
already force-migrated to the fallback (ChatGPT-account Codex rejects it),
so offering it was incoherent. The 5.2/5.1 family stays — those models
remain available to API-key Codex users.
- Per-model reasoning-effort gating: the catalog (now in
packages/ui/utils/codexModels.ts, re-exported from AgentsTab) carries each
model's supported efforts and default effort from the CLI catalog. The
reasoning pickers only offer the selected model's efforts, including the
new max/ultra tiers on the GPT-5.6 family, and useAgentSettings clamps an
unsupported saved effort to the model's catalog default before it reaches
the pickers or a launch payload.
- Drop `minimal` everywhere: no current Codex model supports it. Saved
perModel reasoning entries migrate minimal -> low, and the guide repair
launch no longer hardcodes it.
- Ask AI: bump the codex-app-server static fallback model and DEFAULT_MODEL
from gpt-5.4 to gpt-5.6-sol (runtime model/list discovery still replaces
the fallback and already carries per-model efforts; added Max/Ultra labels).

* fix(agents): prune API-shut-down Codex models per OpenAI deprecations
OpenAI's API deprecations page schedules an API-level shutdown on
2026-07-23 for gpt-5.2-codex (-> gpt-5.5), gpt-5.1-codex-max (-> gpt-5.5),
and gpt-5.1-codex-mini (-> gpt-5.4-mini) — dead for ALL auth modes, not
just ChatGPT accounts — so they leave the picker and saved picks migrate:
the first two to the surface fallback (already gpt-5.5), codex-mini to
gpt-5.4-mini with its perModel preference carried under the new key (same
pattern as the gpt-5.6 -> gpt-5.6-sol rename).
gpt-5.2 stays selectable with no migration: it was retired from the
ChatGPT product (steered to 5.5) but the API still serves it, so API-key
Codex users retain it.
