Hermes 2026-09 moved DEFAULT_TOOLSETS out of tools.delegate_tool into tools.delegate_tool_toolsets. Reading dt.DEFAULT_TOOLSETS now goes through the plugin-compat shim and emits HermesPluginCompatWarning on every load; the shim is removed on 2026-09-14, after which the old path raises AttributeError and the code_intel force-append would silently stop working (swallowed by the surrounding try/except).

Import the new module directly, falling back to the old location so the plugin keeps working on pre-2026-09 Hermes builds.

Thanks for the compatibility fix! Merged as 52e738f.

Verification:

• Clean merge onto current main; only init.py changed (+9/-2). Published tree matches the isolated verification tree exactly.
• New import path, legacy fallback, and append-once behavior checked during review, including registration against installed Hermes.
• Approved the pending fork workflow; PR CI passed on Python 3.10–3.13: https://github.com/rewasa/hermes-code-intel-plugin/actions/runs/34037413503
• Post-merge main CI also passed on Python 3.10–3.13, including real LSP checks: https://github.com/rewasa/hermes-code-intel-plugin/actions/runs/35577645889

This keeps the delegate integration working when the deprecated DEFAULT_TOOLSETS shim is removed while retaining compatibility with older Hermes builds.
