Subject: [PATCH] chore: replace chalk with picocolors

Replace chalk (136KB + deps) with picocolors (3.8KB, zero deps) for
terminal color output. picocolors provides the same core API with
significantly smaller footprint.

All chained style calls (e.g. chalk.red.bold) are converted to
function composition (e.g. pc.red(pc.bold(...))).
