AIProxyOauth 4.2

Discover provider-reported model limits and capabilities, and export client
configuration for Codex and pi.

Changes:

Extend the OpenAI-compatible /v1/models response with OpenRouter-style
context/output limits, names, input modalities, and supported parameters.
Add aiproxy metadata for provider-qualified IDs, source, fetch time,
reported capabilities, reasoning efforts, endpoints, and Codex auth profile.
Retain Codex catalog metadata alongside cached model IDs and account filters.
Read Anthropic limits from the catalog instead of assuming 200K context.
Omit unknown limits and validate optional metadata without exposing raw
upstream catalog objects or model instructions.
Preserve native Anthropic model responses for Claude Code.
Add scripts/export-client-config.py (Python 3.11+) for Codex TOML and pi
models.json snippets. Keep credentials in environment variables.
Run all offline Python tooling tests in the release workflow.

Compatibility:

Existing OpenAI model fields, IDs, routing, and explicit overrides remain.
Extra model fields are extensions; clients may need explicit configuration.
The exporter requires verified overrides for missing required token limits.
pi's standard adapter cannot use native Codex auth because it sends output
limits that the native profile rejects. Use another supported route.
Claude Code's native model picker still does not list Copilot models;
use explicit Copilot IDs advertising /v1/messages.
Live client behavior and live account metadata were not verified.

Validation:

Requires Java 21 and an account with access to the selected provider/model.
See README.md for model metadata and client configuration instructions.
