feat(cli): add run phase timings ⏱️

[timfennis]

Summary

• add a --time flag to ndc run to print lexing, parsing, analyser, compiling, and running timings
• keep phase timing independent from the existing trace feature
• move timing bookkeeping into a dedicated interpreter timing module to keep the interpreter pipeline readable

Verification

• cargo fmt --all
• cargo test -p ndc_bin -p ndc_interpreter
• cargo run -p ndc_bin -- run --time tests/programs/014_comprehensive/001_for_capture.ndc
