Rename CARE agents to descriptive names and add description fields to match agents on Alpha release

[sanzog03]

Summary

Renames all CARE agents from internal naming conventions (e.g., CMRCareAgent, AstroSearchAgent, PDSSearchAgent) to more descriptive, user-facing names (e.g., CMRDataSearchAgent, AstroDataSearchAgent, PlanetaryDataSearchAgent) reflecting the ones in akd-alpha. Also adds CodeSearchAgent to the public API and includes new tests for it.

What it does

• Renames agents to clearly communicate their purpose:
  • AstroSearchAgent → AstroDataSearchAgent
  • CMRCareAgent → CMRDataSearchAgent
  • PDSSearchAgent → PlanetaryDataSearchAgent
  • CodeSearchAgent (newly exported)
• Replaces print statements with loguru logger in agent __main__ blocks.
• Updates all references in docs (CONTRIBUTING.md, HUMAN-IN-THE-LOOP.md) and tests to use the new names.

How it does this

• Renames classes, input/output schemas, and config classes across all four agent modules (astro_search_care.py, cmr_care.py, pds_search_care.py, code_search_care.py).
• Updates akd_ext/agents/init.py to export the renamed classes and adds CodeSearchAgent to the public API (__all__).
• Updates documentation files to reflect the new class names.
• Updates all corresponding test files to import and use the renamed classes.

Testing

• Updated all existing agent tests to use the renamed classes.
• Added new test file tests/agents/test_code_search_care.py with parametrized test cases for CodeSearchAgent.
• All 30 tests pass with uv run pytest ./tests/agents/.

@sanzog03 thanks for this. Along this line: can you also test the "config.name" field to see if it reflects on what we wnat the name to be when frontend displays?

Also: akd_ext.agents.data_search namespace should be there.
