Subject: [PATCH] feat: add ctx_size to context length keys for Lemonade server
 support

- Adds 'ctx_size' field to _CONTEXT_LENGTH_KEYS tuple
- Enables hermes agent to correctly detect context size from custom LLMs
  running on Lemonade server that use this field name instead of the
  standard keys (max_seq_len, n_ctx_train, n_ctx)
