On Arch-based systems (pacman present), paru-build offers yay or
makepkg as install methods. On non-Arch systems neither pacman nor yay
exist, so no methods are built and the dep is silently skipped — no
prompt shown to the user.
Catalog: clear paru's pm and special install entries so it appears in
status but fish-deps install skips it (it's a package manager, not a
managed dep).
Install: cargo is now always attempted first for Rust tools. When cargo
is absent but a crate exists, a note is printed suggesting rustup.
When only one method is available the chosen method is shown so the user
can see whether cargo or the system PM is being used. Method prompt now
shows the default label inline for clarity.
Removed dead paru-build switch case from the install executor.
Split _fish_deps_pm.fish into one file per function so Fish can
autoload each by name (_fish_deps_detect_pm, _fish_deps_pm_install,
_fish_deps_pm_upgrade). A single file with multiple functions only
autoloads under the filename, leaving the others unreachable.
Replace all `test -a`/`test -o` binary operators with `; and`/`; or`
chains throughout _fish_deps_install and _fish_deps_update. Fish 4.x
removed support for -a/-o in test, causing the "unexpected argument"
errors seen on Debian.
Also consolidate paru/yay cases in pm_install and pm_upgrade since
both helpers use identical flags.
yay uses the same -S --noconfirm interface as paru. Detection priority
is paru > yay > pacman so paru is preferred when both are present.
When installing paru itself via paru-build special, yay -S paru is
offered as a method when yay is available, in addition to the
makepkg-from-source fallback.
