fix(lazy_deps): unpin huggingface-hub to a range so refresh stops breaking Hindsight

tool.trace_upload pinned huggingface-hub==1.2.3, but huggingface-hub is a
shared dependency: transformers (via sentence-transformers, the Hindsight
local-embeddings provider) requires huggingface-hub>=1.5.0,<2.0.

active_features() flags a feature as active from mere package presence,
so having sentence-transformers installed marks tool.trace_upload active
even for users who never ran a trace upload. On the next hermes update,
_refresh_active_lazy_features() sees the ==1.2.3 pin unsatisfied and
downgrades the shared package, breaking Hindsight startup with
ImportError: huggingface-hub>=1.5.0,<2.0 is required.

Widen the pin to huggingface-hub>=1.2.3,<2.0 (ranges are the norm in
LAZY_DEPS; the == pin was the outlier): every transformers-compatible
version now satisfies the spec, so the refresh treats it as current
instead of downgrading, and a fresh lazy install resolves to a current
1.x. The HfApi surface trace upload uses (whoami / create_repo /
upload_file) is stable across the whole 1.x line.

Tests pin the invariant: the trace_upload spec must admit every version
transformers accepts (loud failure if someone re-pins it into conflict),
and feature_missing() must report a newer in-range hub as satisfied.

Fixes #60783
