* fix(stream-gears): write the cached GOP on disconnect, flush before the segment hook
The httpflv loop kept the current GOP in `flv_tags_cache` and only wrote it
when the next keyframe arrived. On EOF, a 30 s read timeout or a parse error
the function returned and the cache was dropped, so every disconnect,
reconnect and stream end lost the last 1-10 s. The loop now runs in an inner
function; whatever way it exits, the complete tags in the cache are written
before the original result (including the error) is returned.
`FlvFile` / `TsFile` renamed the `.part` file and ran the segment hook before
the old `BufWriter` was flushed, so the hook (FileValidator, upload) could see
a truncated file, and a failed final flush (disk full) was swallowed. Both now
go through `finish()`: flush and check the error, then rename, then run the
hook. `create_new` returns the flush error; `Drop` logs it with `error!`.
Tests: the rolling-segment test now expects 120 keyframes on disk (was 119)
and checks the size seen by the hook equals the final size; new cases for a
stream that ends cleanly, a read that times out and a parse error; a TS hook
size test; a failed-flush test.

* feat(recorder): default to mesio when no downloader is configured
Rooms without a `downloader` setting followed the plugin hint, which is
stream-gears for almost every platform. They now use mesio: its FLV output
carries `onMetaData.keyframes` and every segment starts at timestamp 0, so
players can seek; it also records HEVC / Enhanced-FLV and HLS fMP4, which
stream-gears cannot. Only the hint mapping in `core/live.rs` changes; an
explicit `stream-gears` keeps using stream-gears, and plugins that hint
streamlink / yt-dlp are unaffected.
`DownloaderRuntime::from_type` no longer has a catch-all arm. `ffmpeg-external`
and `ffmpeg-internal` used to fall into it and silently run stream-gears; both
now run ffmpeg (external segmenting, same as `ffmpeg`). The arm for
streamlink / yt-dlp / ytarchive, which need the live stream and are built in
`downloader_runtime`, is listed explicitly and logs a warning.
WebUI, README, sample configs and CHANGELOG now say mesio is the default and
list the behaviour differences: the container follows the source (HLS fMP4 is
saved as .mp4), files are written under their final name without `.part`, and
Douyu Wangsu reconnects leave a 2.6-5.8 s overlap between segments.

* feat(mesio): pass segment duration and size to the segment callback
mesio's segment-complete callback reports the duration and byte size of each
closed file, but biliup only logged them and built `SegmentInfo` with the path
and index. `SegmentInfo` gains `duration_secs` / `size_bytes` (None for the
other downloaders) and mesio fills them in. The end-to-end mesio test checks
the reported size equals the file size on disk.
Ref #1726
* fix(recorder): parse segment_time the same way in every downloader
`segment_time` was read three different ways. stream-gears indexed
`parts[1]` / `parts[2]` directly, so "3600" or "01:00" panicked the download
task (and an unparsable hour silently became 1); mesio returned 0 for anything
that was not HH:MM:SS and silently recorded without time splits; ffmpeg got
the raw string and accepted both forms.
`parse_segment_time` follows ffmpeg's duration syntax (`[HH:]MM:SS[.frac]`
or plain seconds; minutes and seconds below 60 when colons are used), so all
three downloaders now agree. stream-gears and mesio share
`DownloadConfig::segment_time_limit`: 0 means no time split for both (mesio
already did this; stream-gears used to split at every keyframe), and a value
that still cannot be parsed logs a warning and records without time splits
instead of panicking or being ignored silently. The time-range clamp uses the
same parser, so "3600" is shortened near the window end like "01:00:00".
Ref #1726
* feat(webui): enter file_size as a number with an MB/GB unit
The config still stores bytes. The control converts with 1024 (the same
sizes Windows Explorer shows), keeps an untouched value byte-exact even
when it is not a round MB/GB, and re-picks the unit when the form value
is replaced from outside.
In the streamer override, clearing a value that was already set now
saves null (no size split for that streamer); before, Semi dropped the
emptied key and the old value stayed. Clearing something typed in the
same session still falls back to inheriting the global setting.
* fix(webui): keep the file_size unit beside the number in narrow modals
Add an in-process mesio downloader using the rust-srec mesio-engine. Introduces crates/biliup-cli/src/server/core/downloader/mesio.rs implementing FLV/HLS pull, timestamp fixes, keyframe indexing, and size/duration-based segmentation with pipeline_common, flv_fix and hls_fix. Wire Mesio into downloader enum/runtime and add UI options and public config docs. Update crates/biliup-cli/Cargo.toml and workspace Cargo.toml/Cargo.lock to include new dependencies and bump version to 1.2.5. Include tests for protocol selection, pipeline behavior and an e2e FLV download. Small helper changes: config enum docs and segment handling.
Make file_size and segment_time optional and normalize/validate their values so segmentation can be disabled. Frontend: send nulls for empty fields and allow empty segment_time via validation; add showClear to inputs. Downloader: extend SegmentInfo with optional danmaku_file_path and propagate it from various downloaders; DanmakuClient::rolling now returns a bool to signal whether a danmaku file was produced. Uploader: add segment_paths helper to include danmaku files in upload/postprocessing, and preserve processed paths; add unit tests. HookStep: stream child process stdout/stderr as raw bytes to terminal and append to a log file (tee), and simplify run/move logic to use explicit path lists. Cargo.toml: bump reqwest to 0.13.4. Tests and minor adjustments added throughout to support these changes.
Introduces a pause/resume button for streamers in the UI and backend, including API endpoint and status handling. Refactors streamer status display, updates related TypeScript interfaces, and improves modal forms. Also updates @douyinfe/semi-ui and related dependencies to v2.86.0, and bumps workspace version to 1.1.10. Minor logging and trait changes in Rust backend for improved clarity and error handling.
