add 24 test cases covering all benchmark functionality:
- Benchmark.measure and Benchmark.realtime
- Benchmark::Tms class and its methods (total, to_s, format)
- Benchmark.bm for formatted comparison reports
- Benchmark::Report class
- memory tracking with ObjectSpace integration
- consistency and realistic usage scenarios
suppress output during tests by temporarily setting $stdout to nil
for tests that call Benchmark.bm or Report#report to avoid printing
garbage during test execution.
all tests pass successfully.

fix implementation to work correctly in mruby:
- use String#% instead of sprintf for formatting
- use $stdout directly for output instead of bare print/puts
- add nil check for $stdout to handle test environments
- use Object.const_defined? instead of defined? keyword
- create new Tms instance with label instead of instance_variable_set
- add dependencies: mruby-sprintf and mruby-io
