feat(v1.1.0): adapt to DSH 2.0.10 (0.1.5-rc.2), drop apes:tasks, DSW token styles

C1-C5 env repair:
- align all @deepseek-ai/dsh-* peer+devDeps to 0.1.5-rc.2 (DSH 2.0.10 ships it)
- fix 0.1.5-rc.2 npm packaging defect: 15 primitives runtime deps (anser,
  shiki, katex, marked, ... ) were mis-declared as devDeps in the published
  package -> add to local devDependencies so vitest can resolve them
- fix sidechat-seed contract: dsh-session@0.1.5 assertAssistantSettlementShape
  now requires a top-level data.stream: Array on assistant messages -> seed
  helper emits stream: []

C6 slim tabs:
- remove apes:tasks (overlaps the official DSH session tree in the native
  sidebar); keep apes:agents / apes:apps / apes:profile
- clean dead code: ApesTasksView + job helpers import + apes i18n dead keys
  (tasks/status/duration) and the unused menu-title keys

C7 style align:
- apes view inline colors -> DSW alias tokens (--dsw-alias-bg/border/label/
  state-success/interactive) with literal fallbacks; geometry (font/spacing/
  radius) stays inline (DSH exposes no --ds-* geometry tokens to plugin panels)
