* improve(ui): fold the new-session targets into click menus
The /new target controls become Cursor-style trigger menus instead of an
inline control row: a folder trigger opens the directory browser as a
floating panel (with editable path in its head for manual entry), and a
where trigger opens one menu holding Gateway/node selection plus the
worktree toggle with labeled base-branch/name fields; the agent picker
becomes a menu when several agents exist. Triggers show live labels
(folder basename, node name, a branch badge when a worktree is on), so
the row stays one quiet line even on phones. Menus reuse the shared
session-menu item styles and the chat composer's details/summary
dismissal contract (outside pointerdown, Escape restores trigger focus).
Node-bound drafts no longer show an inert worktree toggle; the item
disappears because managed worktrees are Gateway-only.
* fix(ui): harden the new-session trigger menus
Review fixes: the folder trigger no longer shows the Gateway workspace
basename for node sessions (an empty node folder means that node's
default directory); sibling menus now close on the details toggle so
keyboard-opened menus stay mutually exclusive; and phone menus anchor to
the trigger row full-width so a wide browser panel under a non-leftmost
trigger cannot overflow the viewport.
* fix(ui): keep filesystem roots visible in the folder trigger
folderDisplayName falls back to the raw path so picking '/' (or a drive
root) labels the trigger instead of leaving it blank.
* fix(ui): give the new-session menus the native-select keyboard contract
Opening a menu moves focus to its first item, ArrowUp/Down wrap through
the items (browser rows included), and Home/End jump to the edges,
restoring what the replaced native selects provided. Re-picking the
checked agent no longer resets the draft (the native select never fired
change for the same option).
* fix(ui): keep native key behavior in menu text fields
Menu arrow/Home/End navigation now ignores events from text inputs so
the browser path, base-branch (datalist), and worktree-name fields keep
their native caret and picker behavior.
* fix(ui): let typed paths apply without a directory listing
Admins on hosts without a working fs.listDir keep manual folder entry:
the browser head input tracks a draft path and Use this folder applies a
typed absolute path even when listing fails; shapeless fs.listDir
payloads render as an empty directory instead of crashing the render.
The folder menu also initializes browser state before the focus hook
captures updateComplete, so keyboard-opened menus focus their first row
as advertised.
* fix(ui): apply exactly the shown browser path
Use this folder now applies the head input's absolute path only; the
draft syncs to every listed directory, so browsing is unchanged while an
edited path can never lose to a stale listing.
* fix(ui): let the browser express host-default directories
Review fixes: a cleared path input now applies '' — the host's default
directory (workspace on the Gateway, home on a node) — restoring the
state the replaced clearable folder textbox could express, and directory
results no longer overwrite a path the user typed while the listing was
in flight. E2E covers clearing back to the node default.
* fix(ui): apply the requested directory during browser navigation
loadBrowser assigns the head input the destination it is fetching, so a
mid-flight Use this folder applies where the user is heading instead of
the directory they just left.
