Help text was a wall of monochrome ASCII. Now section headers print
bold-clay, the program title is brand-orange, each verb's syntax is
tinted cyan, and `(alias: ...)` parentheticals are dimmed so they
read as secondary metadata. The styles helper already gates on TTY +
NO_COLOR, so non-interactive output stays unchanged.
Adds .artifacts/specs/2026-05-02-workspace-view.md — the v0.4.0
spec for a per-user virtual workspace that aggregates reads across
all joined meshes while keeping writes mesh-scoped. Roadmap entry
added under v0.3.0.
