fix: remove litellm/typer/platformdirs from hermes-agent deps (supply chain compromise) (#2796)

litellm 1.82.7/1.82.8 contained a credential stealer (.pth auto-exec
payload). PyPI quarantined the entire package, blocking all fresh
hermes-agent installs since litellm was listed as a hard dependency.

These three deps (litellm, typer, platformdirs) are only used by the
mini-swe-agent submodule, which has its own pyproject.toml and manages
its own dependencies. They were redundantly duplicated in hermes-agent's
pyproject.toml.

Also fixes install.sh to not print 'mini-swe-agent installed' on
failure, and updates warning messages in both install scripts to clarify
that only Docker/Modal backends are affected — local terminal is
unaffected.
