feat: switch fork branch to drop-multi-memory (removes 825-line multi-memory patch)

The feat/drop-multi-memory branch on gortium/hermes-agent drops commits:
- 7f3092e feat(agent): support multiple simultaneous memory providers
- 5ff3223 test(agent): update memory tests for multi-provider support
- d10c19f docs: update memory-providers.md for multi-provider support
- d0627af fix(test): remove test_memory_plugin_e2e.py

Configs already use memory.provider: honcho (single provider),
so multi-memory code path was dead code. Piper TTS patch kept.
