v0.2.3 — External contributor CLI version flag

Backtest Integrity Guard v0.2.3

This patch release ships the externally contributed btguard --version CLI flag from PR #24.

Added

• btguard --version prints the installed package version without requiring a subcommand.
• focused CLI test coverage for the version flag.

Changed

• release smoke testing now verifies both btguard --help and btguard --version.
• deterministic JSON version coverage follows the package version instead of a release-specific literal.

Contributor

Thanks to @sarel-myburgh for implementing btguard --version in PR #24.

Verification

• Python 3.10 / 3.11 / 3.12 CI: pass
• 17 unit tests: pass
• wheel/sdist build: pass
• isolated wheel install: pass
• btguard --version: 0.2.3
