v0.52.0

Added

• /resume in two sections (#141): This folder lists the conversations saved in this
  folder and anywhere in its git repository, also from a subfolder, a worktree or another clone
  (the same first commit). Elsewhere lists the 20 newest from other folders, with each one's
  folder. They're numbered across both. Before, only sessions saved in exactly this folder were
  listed, so starting lcode one folder up made them look lost.
• The context each conversation uses, in the list: 18.2K / 32K (57%) against the current
  window, in yellow when resuming it means a summary first. Sessions now save what they used,
  and the status bar shows it right after resuming. Older sessions get an estimate, marked ~.
• Notes follow a repository that moved, was renamed or was cloned again. A repository's
  notes folder names its first commit (repo.json), and a checkout whose own folder has no notes
  finds them by it. Notes from older versions get the file the first time lcode runs there.
• lcode doctor shows how many sessions are saved, how many for this folder, and where.

Changed

• No memory check when a session ends, by default. Quitting, /clear and summarizing no
  longer wait for a model call asking what's worth remembering. Turn it back on with
  lcode config set memory_check true. /remember, the model's memory tool and saved notes work
  as before, and the conversation is always saved.
• lcode -c continues the latest conversation in this folder, else the latest in its repository,
  and says when that takes it to another folder.
• /resume and lcode --resume leave out sessions from temporary folders that no longer exist,
  such as scripted test runs; /resume all lists them, and everything else.

Fixed

• A session file that isn't a conversation (broken JSON, a list, odd messages) no longer stops
  /resume from listing the others.
