Summary

The default include = **/* was matching every path regardless of where the tsconfig sat, so a referenced sub-project with no files/include of its own claimed files outside its own directory and shadowed the parent's compilerOptions.paths. Combined with the solution-style heuristic treating omitted files/include the same as explicit [], a root tsconfig with references and paths but no include lost its own paths for files it owns via the default glob.

tsc 6.0.3 and tsgo 7.0.0-dev both resolve @app/util → src/util.ts. oxc-resolver 11.19.1 did too; 11.19.2 returns Cannot find module.

Root cause

Two interacting bugs:

1. is_glob_matches(_, GlobPattern::All) short-circuited **/* to true regardless of which tsconfig owned the pattern. Fine when the only caller was the walked-up parent tsconfig, broken after fix(tsconfig): let project references take priority over their parent #1151 started asking references the same question — their **/* then matched files outside the reference's directory.
2. claims_ownership_of's solution-style check used is_none_or(Vec::is_empty), conflating omitted and explicit-empty files/include. Per the TS spec only an explicit [] means "own no files"; an omitted include defaults to **/* and should fall through.

This mirrors typescript-go's structure: getFileNamesFromConfigSpecs expands the default **/* via ReadDirectory(basePath, ...), which is naturally scoped to the project directory — no equivalent "literal **/* matches everywhere" code path exists there.

Changes

• src/tsconfig.rs — GlobPattern::All now checks path.starts_with(self.directory()); is_solution_style requires explicit Some([]) for both files and include. Dead GLOB_ALL_PATTERN constant removed.
• src/tests/tsconfig_project_references.rs — root_paths_apply_to_default_include_files covers the repro.
• fixtures/tsconfig/cases/project-references-default-include/ — minimal fixture matching the issue.

All 294 existing tests still pass.

Closes #1159.
