Move Settings and the snippet editor into the on-demand KSwitcher.Config.exe process.
Repeated launches activate the existing configurator. Closing its last window releases the process and its memory.
Apply settings immediately through validated IPC with the resident process; reject conflicting saves instead of overwriting newer settings.
Keep shortcut capture in the resident hook, with no extra global hooks in the configurator.
Support packaging, validation and rollback of both executables. About now displays the actual application version.

Verified: 170 native checks, 51 input/layout checks, 28 updater/metadata checks and 21 configurator process checks. A local before/after measurement after opening and closing Settings reduced resident working set from about 21.0 MiB to 14.7 MiB. Results vary; total memory is higher while the separate configurator is open.

Upgrade from v0.2.3 or earlier: install this release manually once. The old updater rejects the additional EXE. Exit KSwitcher, extract the entire ZIP into the installation folder, and retain data/ and any customized dictionaries. Keep KSwitcher.exe, KSwitcher.Config.exe and dictionaries/ together. Launch KSwitcher.exe. Subsequent updates support both executables through the tray Update menu.

Download KSwitcher-win-x64.zip. The archive contains both applications, offline dictionaries, documentation and license notices. It does not contain personal settings or clipboard history. SHA256SUMS.txt contains the archive checksum.

This folder holds the latest compiled version; older versions remain in Git history and Releases. To refresh the tracked package from source:

.\build.ps1 -Stage -Test
.\package.ps1 -PublishRelease

Commit the ZIP and checksum together with their source changes. Publish both files as assets of one stable release tagged with the executable version, so the updater can verify it.
