Adds a session_directory extension event that fires before session manager
creation, allowing extensions to customize the session directory path based
on cwd, git branch, or other context.
- Extensions can return a custom sessionDir in the event handler
- CLI --session-dir flag takes precedence over extension-provided paths
- If multiple extensions return a sessionDir, the last one wins
- Enables implementing branch-based sessions as an extension instead of core feature
This provides the extension point needed to implement git branch-based
session directories without adding the complexity to core.
Closes#1729
* 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

Returning { isError: true } from a tool's execute function was silently
ignored - the agent loop only sets isError via the catch block. Fix the
with-deps example to throw instead, add a clear note in the Tool Definition
docs section, and update the Error Handling summary.

Use visibleWidth/truncateToWidth for footer path and stats truncation so wide Unicode text cannot overflow terminal width.
Add regression tests for wide session/model/provider names and document the fix in changelog.
