test: add 687 unit tests covering P1/P2 coverage gaps

[runpod-Henrik]

Summary

• Adds 31 new unit test files with 687 test methods covering P1/P2 gaps from the test plan
• Covers credentials, GraphQL client, resource management, stubs, CLI commands, runtime metrics, circuit breaker, serialization, login flow, and security
• Brings unit test coverage from 35% to 82.5%

Test plan

• All 1923 unit tests pass under pytest -n auto (parallel, matching CI)
• make quality-check passes (format, lint, coverage threshold)
• No new skipped tests introduced
• Flaky stub registry tests marked @pytest.mark.serial to avoid parallel pollution

Test Quality Review

Strengths:

• Comprehensive mocking at correct boundaries (RunPod API, network, filesystem)
• Integration tests use realistic mock pipelines without requiring API keys
• Good coverage of error paths and edge cases
• xfail markers on known bugs (REG-009, REG-010) with proper reason strings

Observations:

• Some test files are substantial (800+ lines) — could benefit from splitting in future
• Integration tests appropriately avoid real deployments while still testing the full pipeline
• Tests follow the existing Arrange-Act-Assert pattern consistently

PR Diff Analysis

• No source code changes (test-only PR)
• No hardcoded secrets
• No print() statements
• Public API surface unchanged
• Coverage increased from ~35% to 83.69%

Recommendation

MERGE

Pure test coverage PR. All CI gates pass across 5 Python versions. Coverage jumped from ~35% to 83.69%. No source changes, no regressions.
