New default model GLM-5.2 (1M-context glm-5.2[1m]) across every Z.AI provider, plus TUI polish: ↑ recalls history, diffs render green/red, full / autocomplete, and /settings values now stick.

Added

• GLM-5.2 — the new default Z.AI model. Added across all four Z.AI
  providers (international + China, subscription + pay-per-use): glm-5.2[1m]
  (1M context — the [1m] suffix selects the million-token window) is now the
  default, with plain glm-5.2 also offered; GLM-5.1, GLM-5 Turbo, and GLM-5
  stay available. Context-window and cost tables include both new ids. (GLM-5.2
  per-token pricing isn't published yet, so /cost mirrors GLM-5.1 for now —
  and on the GLM Coding Plan billing is a flat subscription anyway.) Editor
  clients pick this up automatically over ACP.

Fixed

• /settings values stick now. A block of startup "migrations" ran on
  every launch and silently forced user-chosen values back up — maxTokens
  below 32768, agentMaxDuration below 480 min, API timeout and rate limits —
  so the affected settings were effectively lies. They now run exactly once
  per config (recorded via migrationVersion); after that, what you set is
  what you get.
• ↑ recalls prompt history on an empty input. The status bar has always
  advertised "↑↓ history", but a scroll handler intercepted the arrows first,
  so history recall was unreachable. Arrows now do history (like every shell);
  scrolling lives on PgUp/PgDn and the mouse wheel.
• New messages no longer yank you to the bottom. While you're scrolled up
  reading, incoming messages (every agent action, mid-run) used to reset the
  view to the bottom. The view now stays put and the status bar shows a
  "↓ N new · PgDn" badge until you return.

Changed

• Diff blocks render as diffs. ```diff fences — which the agent emits on
  every edit confirmation — now highlight +added lines green, -removed red,
  and @@hunks cyan. Previously they fell through to JS keyword colors.
• Every command in / autocomplete has a description. 48 of 123 rows were
  blank (the whole scaffold/git/devops family — /component, /pr, /docker, …)
  and 9 bare single-letter aliases cluttered the list. The dropdown is now
  derived from a single command registry, so a command can't ship without a
  description again; the single-letter shortcuts (/c, /t, …) still work,
  they're just not listed.
• ~800 lines of dead UI code removed (an unused parallel chat renderer and
  two unreachable fullscreen screens) — no behavior change, but edits can no
  longer land in the wrong renderer by mistake.
• ACP session/new now returns the prior transcript on resume. When an
  editor client reconnects with fresh: false (e.g. a VS Code window reload),
  the response carries the workspace session's history (user/assistant only,
  mirroring session/load) so the client can repaint the chat instead of
  showing blank while the agent still holds the context. Empty on a fresh
  session; older clients ignore the extra field. Powers Codeep VS Code 2.6.0's
  reload restore.
