v2.14.0

Claude Sonnet 5 replaces Sonnet 4.6 in the Anthropic picker (1M context, the full low→max reasoning-effort range), plus correctness fixes from a full-project audit: the ACP edit-approval diff, per-session naming, Grok effort gating, OpenAI-protocol cache accounting, and a /copy edge case.

Added

• Claude Sonnet 5 (claude-sonnet-5) replaces Claude Sonnet 4.6 in the
  Anthropic model list (and the OpenRouter seed). Same $3/$15 pricing and 1M
  context window; graded /thinking effort (low–max). Sonnet 5 rejects
  non-default sampling params, so a custom /temperature is now omitted for
  it (it would otherwise 400) — matching the Fable 5 / Opus 4.7+ handling.
• Claude Fable 5 (claude-fable-5) is back in the Anthropic model picker
  (and the OpenRouter seed) now that it's available again — Anthropic's most
  capable model, for the hardest reasoning and long-horizon agentic work. 1M
  context, full low–max /thinking effort, $10/$50 pricing in /cost. The
  sampling-param and effort handling were already wired up, so this just re-lists
  it in the picker.

Fixed

• ACP edit approvals showed no diff. The permission dialog shown to Zed /
  VS Code branched on old_string/new_string, but the edit_file tool emits
  old_text/new_text — so in Manual mode you approved an edit seeing only the
  file path, not the change. Now reads the real parameter names.
• /new reported the new session under the previous session's name. The
  derived display name wasn't cleared on /new, so syncSession/reportStats
  attributed the fresh, unrelated session to the old name on the dashboard.
• reasoning_effort sent to non-reasoning Grok coders. grok-build (the
  default) and grok-code-fast are coders, not reasoning models — the param
  400s, and a 400 there silently dropped the turn into the weaker text-tool
  fallback. They're now excluded from the effort gate.
• OpenAI-protocol cache tokens over-billed in /cost. extractOpenAIUsage
  ignored prompt_tokens_details.cached_tokens, so DeepSeek/OpenAI cache hits
  were estimated at the full input rate instead of the ~0.1× cache-read rate.
• /copy <non-number> (e.g. /copy abc) reported a bogus success and
  cleared the clipboard instead of showing "Invalid block number"; now guarded.
• Streamed agent turns recorded zero tokens on most non-OpenAI providers.
  stream_options.include_usage was only requested for the literal openai
  provider, so DeepSeek/Kimi/Grok/Qwen/GLM/… streamed with no usage block and
  the whole turn logged 0 tokens / $0.00 in /cost and the dashboard. Now
  requested for every OpenAI-compatible provider (as the plain-chat path
  already does).
• An agent run (or ACP prompt) wiped the session's running /cost total.
  Token tracking was destructively reset at the start of each run to compute
  the cloud-telemetry delta, so the status bar and /cost lost all prior
  session usage (and in the ACP server, /cost after a 2nd prompt showed only
  the last one — or nothing). Now uses a non-destructive marker: cloud stats
  still get only the run's delta while the session-cumulative total survives.
• Concurrent ACP sessions mixed each other's token usage. The tracker kept
  one process-wide record buffer, so two sessions on one process (e.g. VS Code
  "New chat" while another turn streams) clobbered and cross-reported totals.
  Each ACP session now accumulates into its own buffer (via AsyncLocalStorage),
  isolating usage while keeping the single-session TUI path unchanged.
