Implement CE-WP-0001 Foundations: TS scaffold, lint boundaries, normalize v1, fixtures

T01 Toolchain — vite + pnpm 9.15 + React 18 + strict TS (ADR-0001).
T02 Folder layout — src/{shared,engine,anchor,source,binder,work,app}/
    mirroring the future subsystem split, with path aliases.
T03 Boundary lint — eslint-plugin-boundaries enforcing the dependency
    edges from wiki/DependencyMap.md §4; verified by a violating fixture.
T04 Canonical normalization v1 — src/shared/text/normalize.ts with
    NORMALIZE_VERSION=1; 10/10 vitest covering ligatures, CRLF, soft
    hyphens (including line-break reassembly), mixed whitespace.
T05 PDF fixture corpus — 7 user-supplied German PDFs in fixtures/pdfs/
    (gitignored binaries) plus a manifest with verbatim known-good
    quotes and page counts, ready for CE-WP-0002 selector tests.
T06 README upgrade — umbrella README points at wiki/docs/workplans
    and documents the dev workflow.
T07 ADR-0002..0006 stubs in docs/decisions/.

Toolchain end-to-end: pnpm install + lint + typecheck + test all green.
