badlogic/pi-mono v0.57.1 on GitHub

Tree branch folding and segment-jump navigation in /tree, with Ctrl+←/Ctrl+→ and Alt+←/Alt+→ shortcuts while ←/→ and Page Up/Page Down remain available for paging. See docs/tree.md and docs/keybindings.md.
session_directory extension event for customizing session directory paths before session manager creation. See docs/extensions.md.
Digit keybindings (0-9) in the TUI keybinding system, including modified combos like ctrl+1. See docs/keybindings.md.

Added /tree branch folding and segment-jump navigation with Ctrl+←/Ctrl+→ and Alt+←/Alt+→, while keeping ←/→ and Page Up/Page Down for paging (#1724 by @Perlence)
Added session_directory extension event that fires before session manager creation, allowing extensions to customize the session directory path based on cwd and other factors. CLI --session-dir flag takes precedence over extension-provided paths (#1730 by @hjanuschka).
Added digit keys (0-9) to the keybinding system, including Kitty CSI-u and xterm modifyOtherKeys support for bindings like ctrl+1 (#1905)

Fixed custom tool collapsed/expanded rendering in HTML exports. Custom tools that define different collapsed vs expanded displays now render correctly in exported HTML, with expandable sections when both states differ and direct display when only expanded exists (#1934 by @aliou)
Fixed tmux startup guidance and keyboard setup warnings for modified key handling, including Ghostty shift+enter=text:\n remap guidance and tmux extended-keys-format detection (#1872)
Fixed z.ai context overflow recovery so model_context_window_exceeded errors trigger auto-compaction instead of surfacing as unhandled stop reason failures (#1937)
Fixed autocomplete selection ignoring typed text: highlight now follows the first prefix match as the user types, and exact matches are always selected on Enter (#1931 by @aliou)
Fixed slash-command Tab completion to immediately open argument completions when available (#1481 by @barapa)
Fixed explicit pi -e <path> extensions losing command and tool conflicts to discovered extensions by giving CLI-loaded extensions higher precedence (#1896)
Fixed Windows external editor launch for Ctrl+G and ctx.ui.editor() so shell-based commands like EDITOR="code --wait" work correctly (#1925)
