Short-circuit `foostore fish` to skip backend initHEADv0.8.1master

The fish subcommand prints a purely static shell-integration script and
needs no backend, cipher, store, git, or shell.  Previously cli.New ran
in main() before dispatch, triggering the KeePass Argon2 KDF and adding
~1.8s to every interactive fish shell startup that sources the script.

Export FishIntegrationScript and dispatch `fish` directly from main()
before constructing the CLI.  Local timing: `foostore fish` drops from
~1.834s to ~0.003s.

Bump version to v0.8.1.
