v0.5.0

Web launcher, tmux power tools & release notes

• web — a browser launcher in your prompt. web <url> opens any URL in your
  default browser. Bare web pops up your saved links — / to search, Enter/1-9
  to open, a add, e edit, d delete. Open saved links by name (web github,
  case-insensitive prefix works). The list lives in ~/.config/phoenix-term/web-list
  and survives updates.
• web dev — localhost picker. Shows every dev server listening right now
  (port + process), Enter opens it in the browser, / searches, r rescans.
• New tmux power tools. Ctrl-A Tab fuzzy-grabs any path/URL/word from your
  scrollback (extrakto, wired to phoenix-clip) · Ctrl-A g toggles a floating
  scratch terminal that survives closing · Ctrl-A * force-kills a hung process ·
  copy-mode o/S open or web-search the selection (tmux-open).
• Release notes popup. After every phoenix-term update, what's-new appears in
  a popup (you're reading it now). Re-read anytime with phoenix-term notes [tag].
• Tab completion for web (saved names + dev) and phoenix-term
  (subcommands, settings --get/--set with live setting keys).
• Popups get rounded LightSeaGreen borders; cheat sheet and README cover everything.
