dekit v0.10.3

• A value tagged !js in dekit.yaml or a fragment is a JavaScript
  expression, computed when the config loads, as in
  FIXTURES: !js std.path.join(ctx.dir, "fixtures"); ctx has the
  file's dir, the runner, and the vars
• vars: in dekit.yaml names values that !js reads as ctx.vars, in
  order
• dekit wait <target> waits until tasks are ready, or with --for exit
  until they have exited, and exits 0, 1 for a failure, or 124 when
  --timeout runs out; --timeout 0 checks once
• --wait on up, start, and restart returns once what they started
  is ready, and on stop, kill, and veto once it is down;
  --wait-timeout bounds it. A failure names the task at the root and
  shows the end of its screen
• std.dekit.wait(target, {for, timeoutMs}) waits from a script
• dekit run x --dep db waits for db when it is not ready yet, instead
  of exiting 1 at once
• A running job shows as running, not ready; ls --json and why
  carry kind
• A stop dekit gave up on, because the process outlived a kill, shows as
  idle (stop timed out), with reason: "kill_timeout"
• RPC: the wait method and feature, kind in task-info, and the
  kill_timeout reason
• A tasks: key that ends in / is a folder: apps/: {collapsed: true}
  lists the apps folder collapsed at first, and a folder stays while it
  is empty
• dekit rm apps removes a folder or a group with everything in it
• The console keeps which groups are collapsed across restarts; H and
  L collapse and expand every group, and the fold action opens,
  closes, or toggles the groups a path or glob names
• ready: {sd_notify: true} counts a task ready when it sends READY=1
  to the socket NOTIFY_SOCKET names, as it would to systemd
• dekit reload brings what changed in dekit.yaml into a running
  project; the console's header says when the file changed and opens the
  reload dialog
• A runner restart, down and up, and a live upgrade bring every task
  back as it was; dekit.yaml is read at a fresh start and by reload
• The console adds, edits, duplicates, moves, and removes tasks: a,
  e, C, J/K or dragging a row, and d; Space or a right click
  opens a task's menu, y copies its command
• Changes made in the console are written back to dekit.yaml in place,
  keeping its comments; what can't be edited safely goes to a coding
  agent (agent: {cmd: [...]} in the user config) or is copied as a
  prompt
• Tasks are listed in the runner's order: a task moved in the console
  stays where it was put, across restarts too
• dekit rm +dynamic removes every task not from dekit.yaml; a
  dynamic tag written in the config is refused
• dekit spawn --cwd is relative to where the command is typed
• The terminal emulator and renderer were rewritten: true color,
  underline styles and colors, hyperlinks, the kitty keyboard and
  graphics protocols, sixel, and output shaped to what the attached
  terminal can show
• Keymap: e opens the edit dialog (show-rename-task still works) and
  C the duplicate dialog; duplicate-task copies without a dialog
• RPC: reload; the update, move, and set-origin commands; add
  takes the task entry under spec; duplicate takes path and
  start; the changed and bad_config error codes; terminal
  capabilities and the cell size on attach, and input as key,
  mouse, paste, focus, and resize events
• The console follows the terminal's light or dark background;
  tui.theme: dark | light in the user config pins it
