* test: add unit tests across 20 modules for coverage push
Add 300+ unit tests covering config, context, evaluation, extensions,
LLM, secrets, tools/builder, and tools/mcp modules. All tests are
pure unit tests (no mocks) exercising serde roundtrips, edge cases,
error paths, and business logic.

* fix(tests): replace hardcoded /tmp paths with tempfile::tempdir
The e2e_metrics_test::test_metrics_collected_from_tool_trace test was
failing because setup_test_dir() created /tmp/ironclaw_metrics_test but
the fixture referenced /tmp/ironclaw_e2e_test/hello.txt (path mismatch).
Added LlmTrace::replace_paths() to substitute fixture paths at runtime,
then converted all 12 test files from hardcoded /tmp/ironclaw_* paths to
tempfile::tempdir(). Tests are now isolated, parallel-safe, and leave no
debris on disk.
Regression test: test_metrics_collected_from_tool_trace now passes
consistently regardless of prior /tmp state.
