v0.8.39

Fixed

Feishu/Lark bridge startup order is guarded. The bridge now keeps
ThreadStore initialized before startup opens persisted thread state, with a
regression test to prevent moving it below its first use.
/model picker opens instantly with the curated list again. Reverted
the v0.8.38 live-catalog rework: the picker no longer makes a blocking
network call on open and once again shows the curated auto /
deepseek-v4-pro / deepseek-v4-flash rows. The /models command still
lists the live provider catalog.
"Approve for session" groups by command family again. Session approvals
are keyed by a lossy, arity-aware fingerprint once more, so approving
cargo build also covers cargo build --release. Denials keep the exact
per-call fingerprint from #1617, so denying one call no longer over-blocks
later, different calls to the same tool.
Docker first-run state directories are writable. The image now
pre-creates /home/deepseek/.deepseek with deepseek ownership so the
documented named-volume launch can create runtime thread state on first use
(#1684).
Runtime API system prompt overrides survive the first turn. Threads
created with a system_prompt override now keep that prompt through
mode/context refreshes before the model request is built (#1688).
Compaction keeps a user text query in tool-heavy histories. Automatic
compaction now pins the latest user text message when the retained tail only
contains tool calls/results, avoiding OpenAI-compatible Jinja template
failures on the next request (#1704).
Pager jumps land at the visible bottom. Pressing G or End in the pager
no longer overshoots the render clamp, so k/Up scrolls upward immediately
afterward, and mouse wheels now scroll pager overlays directly (#1706,
#1716).
Mouse-wheel-as-arrow scrolling preserves composer drafts. When
composer_arrows_scroll is enabled, Up/Down now scroll the transcript even
with text in the composer instead of replacing the draft with input history
(#1677).
Multiline composer arrows move between input lines. Plain Up/Down now
move the cursor within multiline drafts before falling back to input history,
while single-line mouse-wheel-as-arrow scrolling remains unchanged (#1721).
Third-party reasoning_content streams no longer corrupt text output.
Generic OpenAI-compatible providers that stream answer text in
reasoning_content now render it as normal text unless the selected provider
is one whose reasoning-content semantics are supported (#1673).
macOS system theme detection recognizes Light mode. When COLORFGBG is
missing or unusable, theme = "system" now falls back to macOS appearance
detection and treats a missing AppleInterfaceStyle key as Light mode
(#1670).
rlm_open accepts schema-filled blank source fields. Empty file_path,
content, and url strings now count as absent, so calls that provide one
real source no longer fail the exactly-one-source validator (#1712).
Resize keeps transcript paging usable immediately. After a terminal
resize, PageUp/PageDown now use the resized viewport height instead of
falling back to one-line jumps before the next render (#1724).
ACP responses stringify JSON-RPC ids. serve --acp now returns string
ids even when clients send numeric ids, matching Zed's stricter ACP client
expectations (#1696).
