[scheduler] Track bundle size of scheduler packages

[flaviendelangle]

Summary

The bundle size CI step (code-infra/upload-size-snapshot in .circleci/config.yml) was already running, but the entrypoint list in test/bundle-size/bundle-size-checker.config.mjs did not include any scheduler entrypoints. As a result, the bundle size of @mui/x-scheduler and @mui/x-scheduler-premium was never measured or reported in the size-snapshot comment.

This PR enables bundle-size tracking for both scheduler packages, the same way it works for the data grid, charts, pickers and tree view.

Changes

Expose the package root (.) export

@mui/x-scheduler and @mui/x-scheduler-premium only declared kebab-case sub-path exports (./event-calendar, ./week-view, …) and no root . entry, so there was no package-level entrypoint to measure like the other packages have.

• Added ".": "./src/index.ts" to the exports of both packages.
• The build already auto-generated a root entry from src/index.ts (code-infra adds . whenever build/index.js exists), so this mainly makes the root an explicit, declared public entrypoint (and updates the src/index.ts header comment accordingly).

Add the scheduler packages to the bundle-size config

• The package roots (@mui/x-scheduler, @mui/x-scheduler-premium) are added explicitly, mirroring how the other packages list their root.
• The per-component entrypoints are discovered automatically from each package's exports field via a new findComponentsFromExports helper, rather than being hardcoded.
  • The existing findComponents helper scans the build output for PascalCase component folders (e.g. BarChart/index.js). The scheduler uses kebab-case sub-path exports (event-calendar, day-view, …), so findComponents cannot pick them up.
  • findComponentsFromExports reads the exports keys and filters out non-renderable sub-paths (models, locales, theme-augmentation, internals, and use-* hooks). New views are therefore tracked automatically without editing this config.

Resulting scheduler entrypoints (2 roots + 12 components):

@mui/x-scheduler
@mui/x-scheduler/{agenda,day,month,week}-view
@mui/x-scheduler/event-calendar
@mui/x-scheduler/standalone-event
@mui/x-scheduler-premium
@mui/x-scheduler-premium/{agenda,day,month,week}-view-premium
@mui/x-scheduler-premium/event-calendar-premium
@mui/x-scheduler-premium/event-timeline-premium

The internal packages (@mui/x-scheduler-internals, @mui/x-scheduler-internals-premium) are intentionally excluded, consistent with how other *-internals packages (e.g. @mui/x-internals) are not measured.

Testing

• eslint + prettier --check pass on the changed files.
• tsc --noEmit passes for both @mui/x-scheduler and @mui/x-scheduler-premium after adding the root export.
• The config evaluates and produces the expected entrypoints.
