fix(profiles): seed plugins/ for new profiles

[liuhao1024]

What does this PR do?

Makes hermes profile create seed the plugins/ directory for new profiles. _PROFILE_DIRS seeded skills/, memories/, sessions/, skins/, logs/, plans/, workspace/, cron/, and home/ — but not plugins/. Plugin discovery resolves user plugins under $HERMES_HOME/plugins/, and a profile activation swaps HERMES_HOME to the profile directory, so for any profile created by hermes profile create the discovery path was simply absent: a model-provider plugin configured in the profile's config.yaml failed with Unknown provider 'myprovider' even though the same provider worked on the default profile (#88143).

The fix adds "plugins" to _PROFILE_DIRS (one line plus a comment documenting the discovery dependency). Cloned profiles were already covered — --clone copies the whole tree, and #69913 adds explicit plugins/ clone handling — this closes the fresh-create gap.

Type of Change

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

Changes Made

• hermes_cli/profiles.py — _PROFILE_DIRS gains "plugins" with a comment naming _user_plugins_dir() discovery and the failure mode.
• tests/hermes_cli/test_profiles.py — TestCreateProfile gains test_seeds_plugins_dir: a fresh profile contains plugins/, so the discovery path exists end-to-end for model-provider plugins.

How to Test

1. python -m pytest tests/hermes_cli/test_profiles.py -q
2. Observed result: 49 passed, 2 skipped (48 pre-existing + 1 new). A/B guard: with only the hermes_cli/profiles.py hunk stashed, test_seeds_plugins_dir FAILS (plugins/ absent from the fresh profile).
3. Manual repro from the issue: install a model-provider plugin, hermes profile create architect, activate it — plugins/ now exists under the profile home and the configured provider resolves.

AI code review — automated review for reference; please use your judgment.

1. hermes_cli/profiles.py — Positive: adding plugins to the seeded-dirs list is the minimal correct fix, and the inline comment traces the exact failure chain (bug(profiles): hermes profile create does not seed plugins/ — model-provider plugins invisible to non-default profiles #88143 → _user_plugins_dir → "Unknown provider") so the entry's purpose is self-documenting. The test asserts the discovery path end-to-end (plugins/model-providers parent exists), not just the bare directory. No change requested.
