Reach 100% code coverage with minimal test additions

[Copilot]

This PR achieves 100% code coverage by adding focused tests for the three remaining uncovered lines identified in the codebase.

Changes Made

Test Coverage Additions

• ConfigLoader: Added test for boolean environment variable conversion (HOOKS_USE_CATCHALL_ROUTE, HOOKS_SYMBOLIZE_PAYLOAD, HOOKS_NORMALIZE_HEADERS)
• TimestampValidator: Added test for space-separated UTC timestamp format parsing ("2025-06-12 10:30:00 +0000")
• Lifecycle: Added test for the log method accessor to ensure global logger access is covered

Coverage Requirement Update

• Updated spec/unit/required_coverage_percentage.rb from 99% to 100%

Results

• Before: 99.62% coverage (788/791 lines covered)
• After: 100.0% coverage (791/791 lines covered)
• All unit, integration, and acceptance tests pass
• Code linting passes with no issues

Minimal Impact

The changes are surgical and focused:

• Added only 3 new test cases targeting specific uncovered lines
• No changes to production code
• Total additions: 24 lines of test code + 1 line configuration change

Fixes #35.
