feat: add concore doctor command for system readiness checks

Implements a new 'concore doctor' CLI command that performs comprehensive
system readiness diagnostics including:

- Core checks: Python version, concore installation, CONCOREPATH
- Tool detection: C++, Python, Verilog, Octave, MATLAB, Docker
- Configuration file validation (concore.tools, .octave, .mcr, .sudo)
- Environment variable detection for tool overrides
- Dependency checks for required and optional packages

Includes 23 unit tests covering all diagnostic functions.

Closes #495
