Guard the CLI entry's program.parse() behind import.meta.main so the
command module can be imported without running the CLI, then rebuild the
deleted suite across the three tiers ADR 0009 defines:
- unit: parse (core) and render (bin), asserted on return values
- integration: the view command function, asserted on its Result
- e2e: the kitchen binary as a subprocess (exit codes, streams, ANSI
suppression, errors, --help)
Drop the stale test-support.ts coverage ignore and refresh the task's
implementation notes to describe the tiered suite.
Add a bunfig.toml enabling coverage with text + lcov reporters, a
test:coverage script, and gitignore the coverage/ output. Test files and
the test-support helper are excluded so the numbers reflect product code
only.
