[Feature request]: Binding to a popup that shows patterns available as CLI is used

[snafu4]

What do you need?

After entering '-p', can you create some sort of binding (maybe to fzf) so that the list of available patterns pops up. A pattern is selected and lands on the CLI. I don't have the skillset to do this myself (I tried).

Fabric --list already exists

[snafu4]

'fabric -l' just shows a list of patterns, which you then have to remember to type when you want to use that pattern. I'm suggesting a popup (with all of the available patterns shown) after you type '-p' so you just have to select one and it is inserted into the command line.

Maybe figured it out... This has only been tested on WSL2.

1. sudo apt install fzf
2. Add the following to ~/.bashrc

selectpattern() {
    # Define the base directory
    local basedir="./patterns"
    
    # Use fzf to select a sub-directory from the sorted list in descending order
    # Use sed to remove the base directory path from the output before presenting it to fzf
    local selected=$(find "$basedir" -mindepth 1 -maxdepth 1 -type d | sed "s|^$basedir/||" | sort -r | fzf)

    # Check if a directory was selected
    if [ -n "$selected" ]; then
        # No need to extract the basename since we've already manipulated the output
        # Use printf to escape special characters in the directory name
        printf -v escaped_dirname "%q" "$selected"
        
        # Insert the directory name into the command line at the cursor position
        READLINE_LINE="${READLINE_LINE:0:$READLINE_POINT}$escaped_dirname ${READLINE_LINE:$READLINE_POINT}"
        READLINE_POINT=$(( READLINE_POINT + ${#escaped_dirname} + 1 ))
    else
        # If no directory was selected, ensure proper handling
        echo "No directory selected."
    fi
}

# Bind the function to a key combination, for example Ctrl+p
bind -x '"\C-p":selectpattern'

3. to use: CTRL-p whenever you want to list all of the patterns available (from the 'fabric' directory) use the arrow keys to go up/down and hit enter when you find the pattern you want '''

pbpaste | CTRL-p (and select 'extract_wisdom', press ENTER) and the results will be "pbpaste | extract_wisdom" '''

4. Note: CTRL-p can be a quick substitute for 'fabric -l' to quickly see all available patterns.
5. Note: CTRL-p will only work from the directory where 'patterns' is a directory below (i.e. the 'fabric' directory).
6. Note: CTRL-p allows 'fuzzy search' so you can type "predict" and it will show all patterns that have predict in the name

The fabric -l pattern isn't friendly for tools like fzf. It' shows a "Patterns" header and indents all of the results. Can we create some sort of raw flag that just lists the patterns and nothing else without a heading, line breaks, or indentations?

I'm willing to create a PR, but want to be on the same page with @danielmiessler and the mods.
