…em (#1150)

## Summary

Closes #1075.

`rootDirs` entries inherited via `extends` were being normalized against
the caller tsconfig's directory at `build()` time, instead of against
the directory of the config that actually declared them. This broke the
SvelteKit pattern where `tsconfig.json` extends
`.svelte-kit/tsconfig.json` and the latter declares `rootDirs: ["..",
"./types"]` relative to itself.

## Fix

Mirror the established `paths_base` pattern: normalize non-template
`rootDirs` entries at parse time against each config's own canonical
directory (`canonical_path.parent()`). The `build()` step keeps
`${configDir}` template substitution only, so templates still resolve
against the root caller's directory as before.

After this change, `extend_tsconfig`'s existing clone-from-parent is
correct without further work — the parent's entries are already absolute
by the time the child inherits them.

## Verification

Cross-checked against TypeScript 6.0.3 via `tsc --traceResolution`:

- **SvelteKit case (no symlinks)** — TS resolves `rootDirs: ["..",
"./types"]` declared in `.svelte-kit/tsconfig.json` against
`.svelte-kit/`, exactly matching the fixed behavior.
- **Symlinked `extends`** (`node_modules/shared-config` → real-configs)
— TS anchors inherited `rootDirs` at the **canonical** path of the
parent config, matching the `paths_base` precedent landed in #1148.

Verified against typescript-go source
(`internal/tsoptions/tsconfigparsing.go`): `rootDirs` is declared
`IsFilePath: true` and `normalizeNonListOptionValue` calls
`GetNormalizedAbsolutePath(value, basePath)` at parse time per config;
`handleOptionConfigDirTemplateSubstitution` runs once afterward against
the root caller's directory.

New fixture `fixtures/tsconfig/cases/root-dirs-extends/` mirrors the
SvelteKit reproduction; new test `test_root_dirs_via_extends` fails on
`main` (`NotFound("./$types")`) and passes after the fix.
