chore(infra): migrate plugins to Rstack CLI - #31

Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

Inline comments:
In `@e2e/utils.ts`:
- Around line 74-89: Update the waitForServer rejection handler in runDevCommand
to terminate childProcess before rejecting, ensuring startup failures clean up
the spawned process even when useRstackDocServer has not assigned devProcess
yet. Apply the same cleanup behavior to the corresponding startup path around
the later referenced block.

In `@packages/rspress-plugin-align-image/rspress.config.ts`:
- Line 3: Make the in-workspace imports resolve during clean type checking:
update the TypeScript path/package resolution or lint build order for
packages/rspress-plugin-align-image/rspress.config.ts and
packages/rspress-plugin-back-to-top/rspress.config.ts so their package names
resolve to source files or generated dist entrypoints before rs lint
--type-check runs; apply the same resolution fix to both sites.

In `@packages/rspress-plugin-devkit/rspress.config.ts`:
- Around line 3-13: Update the import of
RemarkCodeBlockToGlobalComponentPluginFactory in rspress.config.ts to reference
the package’s source index export instead of the package root, ensuring CI
resolves the factory before distribution build output is available and preserves
strict-safe typing for propsProvider.

In `@packages/rspress-plugin-file-tree/package.json`:
- Around line 43-55: Add the package’s own workspace package as a devDependency
in packages/rspress-plugin-file-tree/package.json, and apply the same
self-referencing dependency fix in
packages/rspress-plugin-gh-pages/package.json. Ensure the build runs before
type-checking the published-name imports in
packages/rspress-plugin-file-tree/rspress.config.ts and
packages/rspress-plugin-gh-pages/rspress.config.ts; those config files require
no direct change.

In `@packages/rspress-plugin-google-analytics/rspress.config.ts`:
- Around line 3-11: Make the self-package import in rspress.config.ts resolvable
before the package is built by configuring the development typecheck path to
target the package’s src/index.ts, or ensure the package build generates
dist/index.d.ts before this config is checked. Update the relevant package or
workspace TypeScript/build configuration while preserving the existing
rspress-plugin-google-analytics import.

In `@packages/rspress-plugin-katex/rspress.config.ts`:
- Line 3: Resolve the local plugin self-imports before documentation
configuration typechecking by using a resolvable source entry or adding an
appropriate source export condition. Apply the same fix to the imports in
packages/rspress-plugin-katex/rspress.config.ts:3-3,
packages/rspress-plugin-live2d/rspress.config.ts:3-3, and
packages/rspress-plugin-mermaid/rspress.config.ts:3-3 so Rstack and TypeScript
resolve each plugin before its built exports and declarations exist.

In `@packages/rspress-plugin-reading-time/rspress.config.ts`:
- Line 3: Make the self-references for rspress-plugin-reading-time,
rspress-plugin-supersub, and rspress-plugin-vercel-analytics resolvable during
docs type checks by adding appropriate source mappings in each package
manifest/exports, or ensure rs lib runs before config validation. Apply the
change at packages/rspress-plugin-reading-time/rspress.config.ts:3,
packages/rspress-plugin-supersub/rspress.config.ts:3, and
packages/rspress-plugin-vercel-analytics/rspress.config.ts:3; all three sites
require the same resolution fix.

In `@rstack.config.ts`:
- Around line 28-33: Remove the global '`@typescript-eslint/no-explicit-any`':
'off' entry from the rules configuration in rstack.config.ts so the
repository-wide lint command enforces the strict-safe TypeScript guideline. If
an exception is required, scope it to only the specific files or patterns that
genuinely need it rather than disabling the rule for all packages.

In `@tsconfig.base.json`:
- Around line 3-7: Enable full TypeScript strict mode by adding "strict": true
to the shared compiler options in tsconfig.base.json, alongside the existing
target and module settings. Review every tsconfig that extends this base
configuration and resolve any type-checking issues introduced by the stricter
checks.

Nitpick comments:
In @.github/workflows/test-Windows.yml:
- Around line 23-26: Update the actions/checkout step in
.github/workflows/test-Windows.yml (lines 23-26) and
.github/workflows/test-macOS.yml (lines 23-26) to set persist-credentials to
false, leaving the existing checkout configuration unchanged.
