fix(cli): respect ZDOTDIR and XDG_CONFIG_HOME in install, doctor, and implode

[mst-mkt]

issue

resolves #890

details

install.sh hardcodes $HOME for shell config paths, ignoring ZDOTDIR (zsh) and XDG_CONFIG_HOME (fish). This PR respects these variables across install, doctor, and implode.

changes

• install.sh
  Use ${ZDOTDIR:-$HOME} for zsh and ${XDG_CONFIG_HOME:-$HOME/.config} for fish. SHELL_CONFIG_UPDATED is now an absolute path, and the source hint displays ~/... or the absolute path accordingly.
• doctor.rs
  Also check $ZDOTDIR and $XDG_CONFIG_HOME locations when detecting profile configuration.
• implode.rs
  Also collect and clean profiles from these custom locations during uninstall.

Tested on deploy preview with ZDOTDIR set to a non-default location. Works as expected.

Nice work! The install.sh and implode.rs changes look good. One issue I noticed in doctor.rs:

The new XDG_CONFIG_HOME block in check_profile_files only fires when XDG_CONFIG_HOME differs from the default ~/.config. But the base code never checks ~/.config/fish/conf.d/vite-plus.fish either — so doctor will never detect a fish shell configuration at the default location. Only users with a custom XDG_CONFIG_HOME will get their fish config detected, which is backwards.

Suggested fix — add a default fish config check before the new ZDOTDIR/XDG blocks (around line 477):

// Also check the default fish conf.d location
let fish_path = format!("{home_dir}/.config/fish/conf.d/vite-plus.fish");
if let Ok(content) = std::fs::read_to_string(&fish_path) {
    if search_strings.iter().any(|s| content.contains(s)) {
        return Some(abbreviate_home(&fish_path));
    }
}

This way doctor detects fish configs regardless of whether XDG_CONFIG_HOME is customized. (This is a pre-existing gap, so could also be addressed as a follow-up.)
