rtk-hermes v1.1.0

Fixes Hermes v0.11+ compatibility issues.

Changes:

• Fix pip entry point: expose the module (rtk_hermes) instead of the register function so Hermes can find register().
• Accept RTK rewrite exit code 3 as a valid rewrite.
• Document Hermes opt-in plugin configuration (plugins.enabled).
• Install instructions now target the Python environment that runs Hermes.
• Add pytest pythonpath config so tests exercise local source.

Validation:

• 30 tests passing.
• Built wheel/sdist successfully.
• Verified entry point loads as module with register.
• Verified real rewrites: ls -la, git status, cat /etc/hosts.
