feat(blocks): extract six full-guide block components

PhasePanel, FleetDiagram, HandoffTable, WorktreeMap, RouteTable,
SkillPackage as static shells. Each takes typed props and renders
server-side markup with the data-* hooks verified by scripts/verify.mjs
(data-phase, data-tree, data-worker, data-route, data-skill-file). No
client:* directives; interactive islands wire up in task 15.

Tokens only. No raw hex or px font sizes (check-tokens passes). The
parent-background seam colour for the gap:1px grid trick in
FleetDiagram is a documented token gap; see component header comment
and the task final report.
