ctx v1.0.2 - Binary version linkage

ctx v1.0.2

Added

• Binary version check at session start - The session-start hook now checks the installed ctx binary version against MIN_BINARY_VERSION (currently 0.3.0). If the binary is a dev build or below the minimum, a warning is displayed prompting the user to run /ctx:setup to upgrade.
• Implemented in both session-start.sh (Linux/macOS) and session-start.ps1 (Windows)

How it works

• ctx version output is parsed at session start
• Dev builds (ctx dev (commit none, built unknown)) show: ctx binary is a dev build - run /ctx:setup to install the release version
• Outdated versions show: ctx binary outdated: vX.Y.Z installed, v0.3.0+ required. Run /ctx:setup to upgrade
• When the plugin needs a newer binary in the future, only MIN_BINARY_VERSION needs updating
