fix(docker): add profiles directory and honor HERMES_HOME env override in entrypoint

[luyao618]

What does this PR do?

The Docker entrypoint.sh hardcoded HERMES_HOME="/opt/data", silently overriding any user-supplied -e HERMES_HOME=/custom value. Users who wanted to customize the data directory location (e.g. docker run -e HERMES_HOME=/custom/path -v /host/path:/custom/path) had their override ignored. Additionally, the mkdir -p bootstrap list was missing the profiles directory, which is required for multi-profile deployments (hermes profile create).

PR #6936 previously addressed missing directories (skins/plans/workspace) but the maintainer explicitly noted "Left HERMES_HOME hardcoded for now". This PR completes the remaining fix.

Type of Change

• 🐛 Bug fix (non-breaking change that fixes an issue)

Changes Made

• docker/entrypoint.sh:
  • Replace HERMES_HOME="/opt/data" with HERMES_HOME="${HERMES_HOME:-/opt/data}" to honor user-supplied env var while keeping the default
  • Add export HERMES_HOME so the variable survives the gosu re-exec (line 29) and reaches the final exec hermes process (line 64)
  • Add profiles to the mkdir -p directory bootstrap list

How to Test

1. Default behavior (backward compatible):

   docker run nousresearch/hermes-agent env | grep HERMES_HOME
   # Should show: HERMES_HOME=/opt/data

2. Custom HERMES_HOME:

   docker run -e HERMES_HOME=/custom/path nousresearch/hermes-agent env | grep HERMES_HOME
   # Should show: HERMES_HOME=/custom/path

3. Profiles directory created:

   docker run nousresearch/hermes-agent ls -d /opt/data/profiles
   # Should exist without error
