Add useful bash helper functions leveraging existing devcontainer tools

[Copilot]

Extends bash/.config/bash/functions with nine new helpers, each following the established patterns (fzf interactive selection, batcat previews, local scoping, usage comments). All dependencies are already installed in the devcontainer.

New functions

• extract() — multi-format archive extraction; complements existing compress() and decompress alias. Handles .tar.gz, .tar.bz2, .tar.xz, .tar, .zip, .gz, .bz2, .xz.

• rgf <pattern> — ripgrep × fzf with batcat line-highlighted preview; natural counterpart to the ff alias (which finds files — this finds content).

  rgf TODO          # browse all TODO matches across files
  rgf -t py import  # restrict to Python files

• mkd path/to/dir — mkdir -p + cd in one step; uses ${!#} for reliable last-argument expansion.

• ps-fzf — fuzzy-pick a running process and send SIGTERM; includes a [y/N] confirmation prompt before killing.

• tldrf — browse all tealdeer pages via fzf with live preview; gracefully errors if tldr is not installed.

• glf [git-log opts] — interactive git log browser; fzf over git log --oneline with a git show diff preview pane. Accepts any git log flags (e.g. glf -n 50 --author=me).

• jqf [file.json] — fuzzy-pick a JSON file (or pass one directly) and pretty-print it with jq colour output piped through batcat.

• envf — fuzzy-search all current environment variables; echoes the selected VAR=value line.

• ghpr — fuzzy-pick an open pull request (shows number, title, author) with a gh pr view preview pane, then checks it out locally. Natural companion to gclone.

Added four more in commit b34a933, all using tools already in the devcontainer:

• glf – interactive git log browser: fzf over git log --oneline with git show diff in the preview pane; accepts any git log flags (e.g. glf -n 50 --author=me)
• jqf [file.json] – fuzzy-pick a JSON file (or pass one directly) and pretty-print it with jq colour output piped through batcat
• envf – fuzzy-search all current environment variables; echoes the selected VAR=value line
• ghpr – fuzzy-pick an open pull request (shows number, title, author) with gh pr view preview, then checks it out; natural companion to gclone
