"""OAuth credential fallback e2e tests.

Tests that OAuth tokens stored globally under 'default' user are properly
injected when WASM tools make HTTP requests. This validates the fix for:
https://github.com/nearai/ironclaw/issues/999

Note: Full routine execution testing is limited because routines are disabled
in the e2e test environment (ROUTINES_ENABLED=false in conftest.py). This test
validates the OAuth + credential injection flow at the REST API level.

Unit tests in src/tools/wasm/wrapper.rs provide additional coverage of the
fallback mechanism itself.
