ci/woodpecker/pr/ci Pipeline was successful
fix(wizard): write PATH to .profile/.zshenv, never .bashrc
getShellProfilePath() preferred ~/.bashrc when it existed, and ~/.zshrc for
zsh. setupPath() in stages/finalize.ts appends the PATH export to whatever
it returns. Debian's default ~/.bashrc opens with

    case $- in *i*) ;; *) return;; esac

so a line appended to the bottom of it never runs for 'bash -lc', for
systemd units, for 'ssh host cmd', or for any agent seat — precisely the
consumers that need the CLI. An install could print its summary and exit 0
while leaving 'mosaic: command not found'. .zshrc has the same problem:
zsh only reads it for interactive shells.

Now ~/.profile, which login shells read and which Debian's copy sources
.bashrc from for interactive shells, so one line covers both. For zsh the
always-sourced file is .zshenv. fish and PowerShell are unchanged.

__tests__/platform/detect.test.ts pins it, including a case asserting that
no shell resolves to an interactive-only rc file. Falsified by inverting
the fix: 5 failed / 1 passed; restored 6/6. Full package suite unchanged at
17 files / 4 tests failing, matching clean origin/next.
