"""Single source of truth for the CLI version string.

|
|
Reads ``vibe-trading-ai``'s installed package metadata when available
|
|
(``pip install -e .`` is enough). For an un-installed checkout (e.g. running
|
|
straight from a clone with ``PYTHONPATH=agent``) it falls back to reading the
|
|
version straight out of ``pyproject.toml`` — so ``pyproject.toml`` is the one
|
|
and only place the version is ever written. There is deliberately no hardcoded
|
|
version constant to drift out of sync on release (issue #156).
