- Replaced unknown model contextWindow/maxTokens sentinels with nullable values across types and catalog data.
- Mapped request token calculations to treat null maxTokens as unlimited output caps.
- Updated remote compaction and context checks to ignore unknown limits by using Infinity/0 fallbacks.
- Adjusted CLI/model registry flows to skip cap enforcement for null limits and render unknown values as '-'.
- Added `omp models` command with `ls`, `find`, `canonical`, and `refresh` actions.
- Removed top-level `--list-models` parsing from CLI args, launch, and main command flow.
- Implemented action-driven model listing with provider filtering, extension loading, and `--json` output.
- Updated unknown provider/model errors and tests to direct users to `omp models` guidance.
