feat: align devDeps to 0.2.0-rc.2 (21 packages)

- Bump 21 @deepseek-ai devDeps from 0.1.5-rc.2 → 0.2.0-rc.2
  (dsh-code-runtime stays at 0.1.5-rc.2 — no 0.2.0-rc.2 published)
- Fix sidechat-routes.ts: source.kind 'plugin' → 'user'
  (0.2.0-rc.2 removed 'plugin' from MessageSourceMap)
- Remove unused SIDE_INJECTION_PLUGIN import
- Fix test fixtures for 0.2.0-rc.2 stricter validation:
  - tool/result message role: 'user' → 'tool'
  - add toolCallId at message top level
  - assertion kind: 'plugin' → 'user'
- Icon migration: Icon*14 → Icon*Regular, Icon*16 → Icon*Medium (19 files)
- SideChatView API migration to 0.2.0-rc.2
- Add 4 new locale keys (sideChatBlockNoExitCode, codeLabel, wrapLabel, unwrapLabel)
- intercept.tsx: guard against undefined matched in SidebarProducedFiles

Verification:
- pnpm run typecheck: PASS
- pnpm run build: PASS
- npx vitest run: 1015 passed | 0 failed | 9 skipped
