PR Review: Address code review feedback for model get/list commands

Overall this is a solid refactoring PR that improves code quality through DRY principles, performance optimizations, and better test coverage. Here's my detailed feedback:

✅ Strengths

1. Good DRY Refactoring

• Extracting isUuid() and findInputByIdGlobal() into src/domain/models/model_lookup.ts removes duplication from model_get.ts and model_validate.ts
• The new ModelLookupResult interface provides a clear return type

2. Proper Domain Placement

• Placing model_lookup.ts in src/domain/models/ is appropriate from a DDD perspective - UUID validation and model lookup are domain concerns

3. Performance Improvements

• Memoizing the Fzf instances in model_list_output.tsx and type_search_output.tsx is correct - recreating the fzf index on every render was unnecessary work
• The useMemo dependency arrays are correct ([models] and [types])

4. Correct Ink Usage

• Switching from ink-testing-library's render to ink's render in model_get_output.tsx is the right fix for production use

5. Good Test Coverage

• model_lookup_test.ts covers valid UUIDs, case insensitivity, various invalid formats, and edge cases (empty string)
• model_list_test.ts covers filterModels with various scenarios (empty query, name/type/id filtering, no matches, empty list)
• Tests follow the project convention: foo.ts → foo_test.ts

6. Code Style Compliance

• Uses named exports (not default exports) ✓
• No any types introduced (the existing AnyOptions type alias is pre-existing and has a lint ignore comment) ✓

🔍 Minor Observations

1. Missing test for findInputByIdGlobal()

The model_lookup_test.ts only tests isUuid(). The findInputByIdGlobal() function is not directly tested. This is understandable given it requires mocking YamlInputRepository and modelRegistry, but worth noting for future consideration.

2. Infrastructure dependency in domain layer

model_lookup.ts imports YamlInputRepository as a type:

import type { YamlInputRepository } from "../../infrastructure/persistence/yaml_input_repository.ts";

While this is only a type import (not a runtime dependency), in strict DDD the domain layer typically shouldn't depend on infrastructure. Consider defining an InputRepository interface in the domain layer that YamlInputRepository implements. This would allow findInputByIdGlobal() to accept the interface rather than the concrete implementation. This is a minor architectural suggestion, not a blocker.

3. The // deno-lint-ignore no-explicit-any comments

These exist in model_get.ts, model_list.ts, and model_validate.ts for AnyOptions. This is pre-existing and not introduced by this PR, but worth cleaning up in a future PR to satisfy the "no any types" guideline.

🧪 Verification

The PR description states:

• deno run test - all 317 tests pass ✓
• deno lint - no issues ✓
• deno fmt --check - properly formatted ✓

✅ Verdict

Approve - This is a well-structured refactoring PR that:

• Reduces code duplication
• Improves performance with proper memoization
• Adds good test coverage
• Follows project conventions

The minor observations above are suggestions for future improvements, not blockers for this PR.
