server.terminal_errors

Terminal error formatting for chirp development server.

Provides structured, human-readable error output for the terminal during chirp run. Replaces raw logger.exception()with clean diagnostics that highlight the useful information.

For startup errors:

Maps known startup exceptions (port conflicts, TLS misconfiguration,
lifespan failures, config validation) to clean, actionable messages
via ``format_startup_error()``.  Returns ``None`` for unrecognised
errors so the caller can fall back to the default traceback.

For Kida template errors:

Calls ``exc.format_compact()`` and adds Chirp-specific context (route,
method, path). Produces output like::

    -- Template Error -----------------------------------------------
    K-RUN-001: Undefined variable 'usernme' in base.html:42

       |
    >42 | <h1>{{ usernme }}</h1>
       |

    Route:  GET /dashboard
    Hint:   Use {{ usernme | default('') }} for optional variables

    -----------------------------------------------------------------

For non-template errors: Uses configurable traceback verbosity (compact/full/minimal) controlled by theCHIRP_TRACEBACKenvironment variable.
