* feat(coding-agent): add fold/unfold to tree branch navigation
Remap left/right arrow keys in the session tree to jump between branch
segment starts (first child of each branching point). Left on a foldable
node (root or segment start) folds it, hiding its descendants. Right on
a folded node unfolds it. Nested fold state is preserved. Search and
filter changes reset all folds.
Folded branches show ⊞ in the connector (├⊞/└⊞) or as a prefix for
roots. Active path marker • appears after the fold indicator.
Add Page Up/Down support for paging through the tree list, consistent
with session selector and config selector.

When Kitty keyboard protocol is not available (e.g. inside tmux), fall
back to xterm modifyOtherKeys mode 2 so that Shift+Enter, Ctrl+Enter,
and other modified keys are distinguishable from plain Enter.
tmux users need to add to ~/.tmux.conf:
set -g extended-keys on
set -g extended-keys-format csi-u
closes#1872
Koffi is only used on Windows for VT input support and fails to build
on Termux/Android and Linux systems without build tools. Moving it to
optionalDependencies allows installation to succeed on all platforms
while maintaining Windows functionality.
The previous lazy-loading change switched to require("koffi") inside
enableWindowsVTInput(). In ESM, require is undefined, so the call
threw and VT input mode was silently not enabled on Windows.
Use createRequire(import.meta.url) at module scope and
cjsRequire("koffi") at the call site. This keeps koffi externalized
for Bun binaries while restoring Windows VT input behavior, including
multiline paste handling.
Changed koffi import from top-level to dynamic require in
enableWindowsVTInput() and added --external koffi to bun build.
This prevents embedding all 18 platform .node files (~74MB) into
every compiled binary. For Windows builds, only the win32_x64
koffi.node is shipped alongside the binary.
Binary size reduction: darwin-arm64 142MB -> 67MB, archive 43MB -> 28MB.
