l0ng-ai 4f4e29dee4 fix(completion): keep a signature's static candidates in remote panes
A remote pane passes no local cwd, and the argument-position branch answered
that by returning nothing at all. The reasoning in its comment only covered
filesystem paths — offering this machine's filenames for a remote command line
— but the code took `complete_signature` down with them, and a signature's
subcommands and flags are static text describing the *command*, not the
machine. `git push` is just as true over SSH.

The cost was not merely a missing menu. A position with no candidates hands
the line to the shell (`handoff_tab_to_shell`, #136), which clears the inline
editor for the rest of that prompt — so every `git <Tab>` in a remote pane
looked like the editor had crashed. Every git position measured as a handoff:
`git `, `git c`, `git checkout `, `git status`.

Generators stay disabled without a cwd, and that exclusion matters more than
the path one: a generator is a local `/bin/sh -c`, so `git checkout <Tab>`
would have offered the branches of whatever repo tty7's own cwd sat in. A
wrong filename fails loudly when it runs; a wrong branch name is plausible
enough to be accepted. Positions that are generator-only now yield nothing and
hand the Tab to the remote's own compsys, which can actually see that host.

Why

  • Fast — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
  • Sessions persist — quit or reboot; your shells keep running, no tmux
  • Editor-grade input — completion, syntax highlighting, history search built in; zero config for zsh, bash, fish, PowerShell
  • Agent-aware — recognizes Claude Code & co. in a pane: status, notifications, session resume

Install

Native builds for each platform on Releases:

macOS …-macos-arm64.dmg · …-x86_64.dmg drag into Applications
Windows …-setup.exe · portable ….zip
Linux …-x86_64.AppImage chmod +x and run — x11/wayland libs bundled

What's inside

Input ghost suggestions from history · explained tab completion · syntax highlighting · multi-line editing · click places the caret · ⌃ R fuzzy history
Window tabs & splits · ⌘ P palette · ⌘ F scrollback search · eight themes · IME
Coding agents per-pane agent detection (~17 CLIs): status dot, notifications, branch + diff, resume after reboot, tray icon that signals "needs your input"
SSH native russh stack: profiles with keychain secrets, SFTP panel, port forwarding, jump hosts

Details for every row: docs/features.md. Keybindings: ⌘ , opens Settings — browse and remap everything, tmux preset included (full list).
