Subject: [PATCH 2/7] Add fuzz test for GitHub expression parser

- Created pkg/workflow/expression_parser_fuzz_test.go with comprehensive fuzz testing
- Added 59 seed cases covering allowed expressions, malicious injections, and edge cases
- Verified fuzz test runs successfully with go test -fuzz=FuzzExpressionParser -fuzztime=10s
- All existing expression safety tests still pass
- Fuzz test validated no panics on ~97k generated test cases in 10 seconds

+go test -run FuzzExpressionParser ./pkg/workflow/

+- **FuzzExpressionParser** (`pkg/workflow/expression_parser_fuzz_test.go`): Tests GitHub expression validation against injection attacks
+  - 59 seed cases covering allowed expressions, malicious injections, and edge cases
+  - Validates security controls against secret injection, script tags, command injection
+  - Ensures parser handles malformed input without panic
+
+**Fuzz Test Results:**
+- Seed corpus includes authorized and unauthorized expression patterns
+- Fuzzer generates thousands of variations per second
+- Typical coverage: 87+ test cases in baseline, discovers additional interesting cases during fuzzing
+- All inputs should be handled without panic, unauthorized expressions properly rejected
+
+**Continuous Integration:**
