dextrace -V reports stale hardcoded version

[haeter525]

Summary

The version string is duplicated in two places that can drift apart: pyproject.toml (package metadata) and src/dextrace/version.py (hardcoded, used by the CLI's --version). In the 26.6.1 release these disagree — pip show dextrace reports 26.6.1 while dextrace -V prints DexTrace 25.10.1. A single source of truth avoids this class of bug.

If you want to read the version of a package, the recommended way is importlib.metadata.version("name").

Root cause

# src/dextrace/version.py
__version__ = "25.10.1"

The bump to 26.6.1 was applied to pyproject.toml but not to this hardcoded literal, so dextrace -V (which reads __version__) shipped the old number.

Fix

# src/dextrace/version.py
from importlib.metadata import version, PackageNotFoundError

try:
    __version__ = version("dextrace")
except PackageNotFoundError:  # running from source tree without an install
    __version__ = "0.0.0+dev"

pyproject.toml becomes the only place a version is declared; the CLI always matches the installed package metadata.

Affected locations

File	Line(s)	Context
src/dextrace/version.py	5	Hardcoded __version__ literal
src/dextrace/cli/main.py	8, 26	Imports __version__, uses it for --version
