feat: support custom HTTP headers for OpenAI-compatible provider (#269)

Add LLM_EXTRA_HEADERS env var (format: Key:Value,Key2:Value2) to inject
custom HTTP headers into every request to OpenAI-compatible endpoints.
This enables OpenRouter attribution headers (HTTP-Referer, X-Title)
and other service-specific headers without code changes.

Closes #179

**NEAR AI** -- Uses the Chat Completions API with dual auth support. Session token auth (default): authenticates with session tokens (`sess_xxx`) obtained via browser OAuth (GitHub/Google), base URL defaults to `https://private.near.ai`. API key auth: set `NEARAI_API_KEY` (from `cloud.near.ai`), base URL defaults to `https://cloud-api.near.ai`. Both modes use the same Chat Completions endpoint. Tool messages are flattened to plain text for compatibility. Set `NEARAI_SESSION_TOKEN` env var for hosting providers that inject tokens via environment.
**NEAR AI Cloud** -- Uses the OpenAI-compatible Chat Completions API (`https://cloud-api.near.ai/v1/chat/completions`). Authenticates with API keys from `cloud.near.ai`. Auto-selected when `NEARAI_API_KEY` is set (or explicitly via `NEARAI_API_MODE=chat_completions`). Tool messages are flattened to plain text for compatibility. Configure with `NEARAI_API_KEY` and `NEARAI_BASE_URL` (default: `https://cloud-api.near.ai`).
**OpenAI-compatible** -- Any endpoint that speaks the OpenAI API (vLLM, LiteLLM, OpenRouter, etc.). Configure with `LLM_BASE_URL`, `LLM_API_KEY` (optional), `LLM_MODEL`. Set `LLM_EXTRA_HEADERS` to inject custom HTTP headers into every request (format: `Key:Value,Key2:Value2`), useful for OpenRouter attribution headers like `HTTP-Referer` and `X-Title`.
**Tinfoil** -- Private inference via `https://inference.tinfoil.sh/v1`. Runs models inside hardware-attested TEEs so neither Tinfoil nor the cloud provider can see prompts or responses. Uses the OpenAI-compatible Chat Completions API. Configure with `TINFOIL_API_KEY` and `TINFOIL_MODEL` (default: `kimi-k2-5`).
