* wrap ggml_backend_load_best in try/catch
* ignore non-ollama paths

ollama requires vcruntime140_1.dll which isn't found on 2019. previously
the job used the windows runner (2019) but it explicitly installs
2022 to build the app. since the sign job doesn't actually build
anything, it can use the windows-2022 runner instead.

the find returns intermediate directories which pulls the parent
directories. it also omits files under lib/ollama.

switch back to globbing

Shield the code processing the embedding result
from subsequent calls that may overwrite the same
buffer to process a second input when retrieving
model embeddings.

* chore: update gitattributes
* chore: add build info source

Removed redundant checks and streamlined the switch-case structure.
Added test cases for both HumanBytes and HumanBytes2 to cover a wide range of scenarios.

In some cases, downloads slow due to disk i/o or other factors,
causing the download to restart a part. This causes the download
to "reverse" in percent completion. By increasing the timeout to 30s,
this should happen less frequently.
