Rename binary from geheim to foostore

- go.mod: module path codeberg.org/snonux/geheim → codeberg.org/snonux/foostore
- cmd/geheim/ → cmd/foostore/
- Magefile.go: binary/binaryName/mainPkg constants updated
- internal/config: config file path ~/.config/geheim.json → ~/.config/foostore.json
- All import paths and comments updated throughout
- Delete geheim.rb (the original Ruby implementation, superseded by this Go rewrite)
- CLAUDE.md rewritten to reflect the Go implementation, new binary name,
  build system (mage), and current package architecture
