v0.4.8

Follow-up to v0.4.7: jumpcall install no longer replaces Homebrew's own CLI symlink.

Previously it swapped /opt/homebrew/bin/jumpcall (brew's link into the Cellar) for its own link into ~/Applications. Brew then refused to link on every upgrade ("possible conflicting files"), leaving a stale binary on PATH — so even a freshly upgraded Cellar build never actually ran. Now a live brew-managed link is left alone (brew keeps it current), and jumpcall uninstall skips it too.

Upgrading from an affected install (the conflict warning means yours is):

brew update && brew upgrade jumpcall
brew link --overwrite jumpcall   # one-time: reclaim the PATH entry for brew
jumpcall install
