v0.9.0

Changed

• Ctrl+R history search is now a browsable menu: matching is fuzzy
  (subsequence with word-boundary/consecutive bonuses; space-separated terms
  must all match) blended with frecency, and the ranked candidates float
  beside the prompt — matched characters highlighted, selection moved by
  Ctrl+R/↓ and Ctrl+S/↑, Enter to edit, Cmd+Enter to run outright. An empty
  query lists the whole history by frecency, so bare Ctrl+R is a "recent &
  relevant" browser. The classic (reverse-i-search) line stays. (#45)
• History records now carry when the command ran and its exit code: new
  entries are <ts>\t<exit>\t<cwd>\t<command>, written when the command
  finishes (zsh INC_APPEND_HISTORY_TIME-style, exit code sniffed from
  OSC 133;D daemon-side); older formats still load. The Ctrl+R menu shows
  "ran 3h ago" and a ✗ badge on commands whose last run failed; timestamps
  from zsh/bash history files are carried over when seeding. (#45)
