Enhance Bash default configuration robustness

[Kasui92]

Following the approach used in Omarchy, reorganized all Bash scripts into /defaults/ directory, made .bashrc easier to modify and introduced preventive checks for aliases relying on packages or libraries that might be uninstalled.

I want to give you some practical advice. In my work, I connect aliases that are clearly linked to applications in this way.

# Load custom aliases
if [ -d "$HOME/.config/aliases" ]; then
    for f in "$HOME/.config/aliases/"*.sh; do
        [ -f "$f" ] && source "$f"
    done
fi

app-lazygit.sh add

    mkdir -p ~/.config/aliases
    printf "%s\n" \
        'alias lzg="lazygit"' |
        tee ~/.config/aliases/lazygit.sh >/dev/null

As far as I'm concerned, they should be tied specifically to installing and uninstalling applications.
