Remove obsolete cmd2 console implementation

[sodejm]

Motivation

• Remove the legacy cmd2-based interactive console and adapters and preserve the default prompt-toolkit/Rich REPL and one-shot CLI paths.
• Reduce a hard dependency on cmd2 and simplify module loading so command execution is handled by the transport-neutral CLI dispatcher.

Description

• Replaced the old src/ancestryllm/console/app.py cmd2 implementation with a small compatibility facade AncestryConsole that subclasses the existing ReplApplication from console.shell and preserves cmdloop() behavior.
• Deleted obsolete cmd2 adapter modules and helpers under src/ancestryllm/console/: command_sets.py, gedcom.py, rootsmagic.py, people.py, prompts.py, ocr.py, secrets.py, and providers.py.
• Updated BUILTIN_MODULES entries in src/ancestryllm/core/modules.py to reference the one-shot dispatcher (ancestryllm.cli:run_tokens) and changed ModuleRegistry.load() to return descriptors without importing the old console adapters.
• Removed cmd2 from pyproject.toml dependencies so runtime no longer requires the obsolete console package.

Testing

• python -m pip install -e . completed successfully in the test environment.
• Compiled the modified modules with python -m compileall and compilation succeeded without syntax errors.
• Ran targeted pytest suites tests/modular/test_repl_shell.py, tests/modular/test_repl_router.py, and tests/modular/test_repl_history.py, and they passed (interactive REPL and router behavior preserved).
• tests/modular/test_command_specs.py still contains a legacy expectation asserting that ModuleRegistry.load() imports the old console adapters, which no longer holds after this refactor; that test must be updated to match the new behavior (current run shows it failing for that legacy expectation).
