  1. [0.159] Prepare 0.159.1 release backports (#49323) 

    Prepare the backports for 0.159.1 on `release/0.159`. The release set is
incomplete: one additional backport is pending. Keep this PR in draft
until the full release set is included.

Currently includes #49318: add GPT-6.1 Sol as the default bundled model
and update the older Sol descriptions and model-picker snapshots.

The backport omits the `skill_catalog_dedup` snapshot because its test
does not exist on the 0.159 release line. The model catalog and all
retained snapshot files match the original public commit.

Release-line CI currently reports a stale `code-mode` feature exception
in the manifest checker, unlinked files in `codex-core` and
`codex-login`, and Codespell findings in the exec-server and TUI math
code. The reported files are unchanged from the 0.159.0 content commit.
A Linux Bazel job also failed while downloading Buildozer with HTTP 500.

  2. [0.159] Backport GPT-6.1 Sol Bedrock catalogs (#49342) 

    Backport #49339 onto `release/0.159` for 0.159.1. This adds GPT-6.1 Sol
to the Bedrock Mantle and Runtime catalogs and makes it the default
while retaining existing models and provider capability normalization.

The bundled catalog dependency is already on the release branch through
#49323. The cherry-pick applied without conflicts and has the same
stable patch ID as the original public commit.

Validation:
- `just test -p codex-model-provider -p codex-model-provider-info --lib
bedrock`: 57 passed.
- `just test -p codex-tui --lib bedrock`: 7 passed; reviewed Mantle and
Runtime model-picker snapshots, including GovCloud coverage.
- `just test -p codex-app-server --test all -E
'test(suite::v2::thread_start::thread_start_provider_model_fallback_) or
test(suite::v2::thread_start::thread_start_bedrock_runtime_)'`: 4 passed
on automatic retry. All four initial attempts timed out during
initialization; nextest reports these as flaky passes.
- `just fmt` completed successfully. Discarded unrelated justfile-only
formatting churn; the backport remains identical to the public source
patch.
- `git diff --check`: passed.
- Live AWS inference has not been verified as part of this backport.

CI remains blocked by failures outside this nine-file backport:
- [Manifest
check](https://github.com/openai/codex/actions/runs/36615506389/job/109567359534):
stale `code-mode` feature exception.
-
[Codespell](https://github.com/openai/codex/actions/runs/36615506389/job/109567359001):
`WRONLY` and `oint` in unchanged exec-server/TUI math files.
- [cargo
shear](https://github.com/openai/codex/actions/runs/36615506389/job/109567775485):
unlinked `core/tests/suite/scenarios_read_only_mcp.rs` and
`login/src/internal_identity.rs`.
- [Bazel
Clippy](https://github.com/openai/codex/actions/runs/36615506389/job/109567360047):
unused imports in unchanged core implementation/test files.
- [SDK
checks](https://github.com/openai/codex/actions/runs/36615506389/job/109567359667):
existing formatter-driver test expects direct rustfmt while the driver
uses cargo fmt; neither file changes here.

Release coordination: include this backport together with #49323 before
publishing 0.159.1. Publication remains with the release captain.
