feat(doc-mode): rename surfaced label "Directive" → "Contract" (#109)

Stage 2: cosmetic UI rename only. Database tables, API paths, hook names,
and CLI commands all stay as 'directive' for now — we'll phase out the
existing standalone /contracts table later.

Surface changes:
- Sidebar header "Documents" → "Contracts"; root folder "directives/" →
  "contracts/"; empty state "No directives yet" → "No contracts yet".
- Editor placeholders, breadcrumb header, "back to document" → "back to
  contract", right-click menu header.
- NavStrip: when documentModeEnabled is on, the "Directives" link renders
  as "Contracts" (href stays /directives so links don't break).
- Save bar message "saving will replan the directive" → "the contract".

No backend changes — directive.goal etc. all still work the same.
