## Summary
- Keep the refreshed bundled prompts for GPT-5.6 Sol, Terra, and Luna.
- Keep the 272,000-token context and maximum context windows for those
three models.
- Revert the unrelated model-catalog metadata changes introduced by
#33972.
## Why
#33972 backported a broader generated catalog refresh than this stable
hotfix needs. The intended `0.144.6` change is limited to the GPT-5.6
Sol/Terra/Luna prompt refresh and their corrected context-window
metadata.
This follow-up restores all other catalog values to the last-green
`release/0.144` baseline. In particular, it removes fields that `0.144`
does not understand, restores the existing skills-guidance settings and
GPT-5.5 availability NUX, and leaves model visibility and upgrade
behavior unchanged.
Relative to `215fb464f1932b5fd7beb5d4615bc1927d80fbf7`, the resulting
catalog differs in exactly 12 values: `base_instructions`,
`model_messages.instructions_template`, `context_window`, and
`max_context_window` for each of GPT-5.6 Sol, Terra, and Luna.
## Validation
- `just test -p codex-models-manager bundled_models_json_roundtrips`
- `just fmt`
- `jq empty codex-rs/models-manager/models.json`
- `git diff --check`
- Verified the semantic diff against
`215fb464f1932b5fd7beb5d4615bc1927d80fbf7` contains only the intended 12
values.
- Verified all retained values exactly match
`d26a9bf671b1c03aabfc32e1092d137c1feb3962`.
