Hephaestus v0.4.6

Highlights

• Hephaestus Network now requires a visible Hub invocation receipt line before substantive work: Hub agent name, slug, routing receipt, and execution id.
• Public demos and distribution flows are explicitly Hub-first/Hub-only, avoiding accidental local Paid/Free inventory routing.
• Bumped runtime, plugin, extension, docs, MCP server, and installer pins to v0.4.6.
• Tightened release bumping so vendor dependency locks are not treated as Hephaestus release pins.
