@fullstack-webapp/document-shell 0.1.0-beta.4

Adds a declarative, package-owned minimum-visible hold for parser-visible document projections.

• Exposes documentShellRevealNotBeforeAttribute from the client entry.
• Honors valid future deadlines only for the normal loaded-stylesheet handoff.
• Keeps error, timeout, absent, invalid, expired, and out-of-horizon paths fail-open.
• Bounds holds against wall-clock rollback with independent wall-clock and monotonic ceilings.
• Preserves document-scoped idempotence and centralized timer cleanup.
