Close audited user-flow gaps and release v0.6.1

[udhawan97]

What changed

• added a compact 320px shell with an accessible Menu, a reserved guidance row, narrow-map auto-fit, and a full-stage Study sheet
• made Modules and Find render from the Star chart instead of leaving latent state
• sequenced first-run onboarding as audience → required Home → coach marks
• made parser-owned 3D nodes non-draggable and guarded stale non-touch pointer state
• bumped every release surface to 0.6.1 and updated the changelog, docs, release notes, Current State, and Decision Log

Why

A real browser audit found four gaps that interrupted the learning loop at narrow widths, in chart navigation, during first-run calibration, and in OrbitControls pointer bookkeeping.

The pointer fault came from 3d-force-graph installing drag controls for immutable nodes; its drag-end bridge injected a synthetic touch release while OrbitControls was completing a mouse release.

Impact

The parser, graph, checks, persistence, local-first boundary, and Formal Edo visual system are unchanged. The full map-to-study loop now works at 320px, global navigation is truthful in every screen, and the 3D canvas no longer emits the audited pointer exception.
