Add comprehensive keyword routing tests to e2e/testcases

Consolidate all keyword routing tests into e2e/testcases for CI integration.

This adds comprehensive testing for keyword-based routing with both
E2E integration tests and unit tests:

E2E Integration Test (keyword_routing.go):
- Registers as 'keyword-routing' testcase for Kind-based CI
- Makes HTTP requests to router service via port forwarding
- Validates classification via X-VSR-Category header
- Tests 26 scenarios with 80% accuracy threshold

Unit Tests (keyword_routing_test.go):
- 35 comprehensive unit tests using Ginkgo/Gomega
- Tests OR, AND, NOR operators
- Validates case sensitivity and word boundaries
- Tests regex special characters and edge cases
- Tests error handling and multiple rule matching

Test Data:
- keyword_routing_cases.json - 26 E2E test scenarios
- embedding_routing_cases.json - Embedding test data
- hybrid_routing_cases.json - Hybrid routing test data

Helper Functions (helpers.go):
- CreateKeywordTestRules() - Standard test rule definitions
- CreateTestKeywordClassifier() - Test classifier factory
- Test suite configuration (suite_test.go)

Changes:
- Move tests from e2e-tests/testcases to e2e/testcases
- Remove old e2e-tests/testcases directory
- Update .gitignore to remove e2e-tests/testcases references

This addresses reviewer feedback to consolidate tests in e2e/testcases
for proper CI integration.
