Owner decision 8 ("when I hit the tiles button, open the tiles already!").
A click with the grid closed now opens it straight away, and Ctrl+Shift+G
runs the same function (toggleTileGrid), so the two cannot drift. What
opens comes from one pure helper, tileGridOpenSet (constants.js):
a. the grid this tab last had, if any of its sessions survive, opened
exactly (an open split closes and its sessions do not join);
b. else an open split's two sessions, Pane A focused;
c. else the open sessions in tab order (the picker's list: no detached
ones), up to what the grid takes here (the cap of 6, fewer when the
window fits fewer), the active session always among them and focused.
A click with the grid open still closes it.
The picker moved to right-click (oncontextmenu, browser menu suppressed).
With the grid open it is preselected with the current tiles, and Open
replaces them. Ctrl/Cmd+click on a tab with the grid closed opens the
toggle's set plus that session. The button's title, the Help modal and
the wiki say right-click chooses which sessions.
Docs: decision 8 and an as-built entry in the spec (Entry points too),
CLAUDE.md, the invariants (#tile-grid, Opening), the wiki's Tile Grid and
Keyboard Shortcuts pages.
