Adds the routing scaffold for the doc-centric pivot. Each new route
renders a placeholder page until E3/E4/E5 implement them; legacy
routes (/studio, /documents, /history, /search, /reasoning) keep
working in parallel.
New routes (Vue Router, history mode):
/docs library (placeholder, #211)
/docs/new import (placeholder, #214)
/docs/:id?mode= workspace (placeholder, #216)
/index stores list (placeholder, 0.7.0)
/index/:store store detail (placeholder)
/index/:store/query RAG playground (placeholder)
/runs run history (placeholder)
/runs/:id run detail (placeholder)
Mode parsing
- shared/routing/modes.ts: DocMode union ('ask'|'inspect'|'chunks'),
parseMode() returns the default ('ask') for missing or unknown
values. #210 will layer feature-flag-aware redirection on top.
Route names
- shared/routing/names.ts: ROUTES typed const so callers do
router.push({ name: ROUTES.DOC_WORKSPACE, ... }) instead of
stringly-typed names.
Pages
- ComingSoonShell shared component: card + back-home link, themed
with existing CSS tokens.
- 8 thin placeholder pages (one per new route) that compose the shell
and forward route params.
- i18n keys under comingSoon.* added in fr + en.
Tests
- shared/routing/modes.test.ts (10 cases): isDocMode + parseMode +
ALL_MODES invariants.
- app/router/router.test.ts (5 cases): every doc-centric route
resolves to a component, legacy routes still work, doc workspace
receives id and parsed mode as props, unknown mode falls back to
ask, unknown path redirects to home.
Routes table extracted to routes.ts so tests build a router with
createMemoryHistory() (no window required) instead of needing the
production createWebHistory() router.
