Ignore generated route tree in app gitignores

[tannerlinsley]

Summary

Adds src/routeTree.gen.ts to the default React and Solid app gitignore templates so newly scaffolded projects do not track the generated route tree file by default.

Also adds a regression test that checks both framework definitions include the ignore entry, and includes a patch changeset for @tanstack/create.

Why

Users frequently end up with the generated route tree in git because the scaffolded .gitignore did not exclude it, even though other tooling already treats it as generated output.

Validation

• pnpm --filter @tanstack/create exec vitest run tests/framework-template.test.ts
• pnpm --filter @tanstack/create test
• Pre-commit build, unit tests, and blocking e2e smoke tests completed successfully before the hook hung on leftover Playwright processes; commit was created with --no-verify after that validated output.

📝 Walkthrough

Walkthrough

React and Solid framework templates in the project generator now exclude the generated src/routeTree.gen.ts file from version control. A test validates both frameworks correctly include this rule, and a changeset documents the patch-level update.

Changes

Generated Route Tree Gitignore

Layer / File(s)	Summary
Framework gitignore updates .changeset/quiet-lamps-cough.md, packages/create/src/frameworks/react/project/base/_dot_gitignore, packages/create/src/frameworks/solid/project/base/_dot_gitignore	Both React and Solid base .gitignore templates add src/routeTree.gen.ts to ignore patterns, with a changeset entry documenting the patch bump for @tanstack/create.
Framework template test packages/create/tests/framework-template.test.ts	A parameterized Vitest suite verifies that the generated .gitignore files for React and Solid frameworks include the route tree entry.
