When transcribing with params.vad = true, whisper already computes the speech
segments and keeps them in the state. Expose them so callers can reuse those
boundaries (for example to align or clip subtitles to speech) instead of running
a second, separate VAD pass.
Times are on the original audio timeline in centiseconds; the count is 0 when VAD
was not used. test-vad-full.cpp checks the segments are ordered and non-empty.
whisper_full_get_token_data().t0/t1 are in the VAD-processed timeline (silences
removed), so they don't line up with the original audio. Add
whisper_full_get_token_t0/t1 that map them back.
A token inside a speech segment is interpolated within it; a token that falls in a
removed inter-segment silence snaps to the nearest boundary, so it never lands in
the middle of a cut-out gap. Without VAD the raw times are returned unchanged.
whisper_vad_detect_speech resets LSTM state on every call, which is
correct for batch processing but prevents temporal continuity when
calling per-chunk in a streaming loop.
Add whisper_vad_detect_speech_no_reset (skips buffer clear) and
whisper_vad_reset_state (explicit clear between utterances).
Existing whisper_vad_detect_speech is now a thin wrapper — zero
behavior change for current callers.

* whisper : add version function
This commit adds a version function to the whisper API.
The motivation for this is that it might be convenient to have a way to
programmatically check the version.
Example usage:
```c++
printf("Using whisper version: %s\n", whisper_version());
```
Will output:
```console
Using whisper version: 1.7.6
```
* examples : add version to android example CMakeLists.txt
* vad : add initial Voice Activity Detection (VAD) support
This commit add support for Voice Activity Detection (VAD). When enabled
this feature will process the audio input and detect speech segments.
This information is then used to reduce the number of samples that need
to be processed by whisper_full.
