fix: align doctor with auth-store and enabled tools

[shokirunicus]

Summary

• treat logged-in auth-store/OAuth providers as configured in doctor without requiring raw API keys in .env
• limit doctor auth-store probes to auth-backed provider types so API-key/AWS SDK credential chains are not triggered
• filter Tool Availability diagnostics to CLI-enabled toolsets and ignore the local .install_method stamp

Tests

• git diff --check HEAD
• venv/bin/python -m py_compile hermes_cli/doctor.py tests/hermes_cli/test_doctor.py
• HOME=/Users/purpl uv run --extra dev ruff check hermes_cli/doctor.py tests/hermes_cli/test_doctor.py
• HOME=/Users/purpl uv run --extra dev python -m pytest tests/hermes_cli/test_doctor.py -q -o 'addopts=' (70 passed)
• hermes doctor (All checks passed)
• changed-line secret scan (hits=0)
• added-line absolute path scan (hits=0)
• independent read-only code review (PASS)

Thanks for the auth-store doctor investigation. The underlying OAuth-without-.env problem remains on current main: hermes_cli/doctor.py:704-715 only checks .env provider hints before treating the configuration as missing.

Problems

• Current main intentionally filters only the final missing-API-key summary, while retaining tool-availability rows (hermes_cli/doctor.py:2195-2200, commit 6b21a935). The PR instead filters both displayed lists at proposed hermes_cli/doctor.py:2148-2151; this needs an explicit UX decision during salvage.
• The added delegation regression test does not reach its new fallback: proposed tests/tools/test_delegate.py:389 passes a non-empty model, which the existing expression already uses. The real dispatcher passes resolved creds["model"] at tools/delegate_tool.py:2522.
• .install_method is already ignored on main at .gitignore:121-124.

Suggested changes

• Preserve the auth-store doctor fix, but reconcile the tool-row behavior with 6b21a935.
• Drop the unrelated delegation change unless a reachable falsey-model path can be demonstrated and tested through the real credential-resolution flow.

Automated hermes-sweeper review.

Current main deliberately filters only the final missing-API-key summary (commit 6b21a935), while retaining all tool-availability warning rows. This filters the displayed rows as well; please reconcile that UX change with the current-main behavior rather than applying it incidentally.

[teknium1]

This supplies a non-empty model, so both the old and new callback-label expressions select it before reaching the added fallback. The test passes on pre-change code; either demonstrate a reachable falsey-model flow through credential resolution or drop the dead branch.
