Search improvements with daemon

The daemon, previously experimental, now maintains a hot, in-memory search index powered by a modified version of nucleo, which implements the same algorithm as fzf. Configurable multipliers for frequency, recency, and frecency scoring are available. Enable with:

search_mode = "daemon-fuzzy"
[daemon]
enabled = true
autostart = true

With autostart enabled, Atuin manages the daemon lifecycle. The daemon also enables syncing records without shell interaction, keeping remote machines updated.

Atuin AI for shell commands

Press ? on an empty prompt, describe what you want, then press enter to execute or tab to edit. Press f to follow up with adjustments or questions. Enable with:

[ai]
enabled = true

Accuracy comes from frontier models combined with a dataset powered by man pages and command outputs. Safety checks flag dangerous commands (like wiping data or restarting deployments) requiring double enter to execute. Data privacy is minimal by default—only OS and shell info—with optional permissions for directory path, contents, git status, etc.

PTY proxy (hex)

Hex enables Atuin popups to render over previous terminal output without clearing it, unlike previous fullscreen or inline modes. It's a lightweight PTY proxy that behaves like minimal tmux but doesn't affect scrollback or break terminal features. Enable one-off with atuin hex or permanently with:

eval "$(atuin hex init)"

Future uses include searching/syncing command outputs, supporting shells without hooks, and readline-esque features.

Other updates

New authentication for hosted sync service (Atuin Hub) adds Google/GitHub login and email recovery. Existing credentials still work. Hub isn't open source yet due to rapid changes. Self-hosting remains unchanged.
