ForgeFlow 4.6.2: Complete local shipping previews

Shipping previews now include staged and unstaged edits and nonignored new files alongside committed branch changes. Previously, uncommitted work could be missing from the preview.

• Each path appears once, and the reported count uses the same inventory.
• Staged changes remain visible when an unstaged edit restores the base content.
• Filenames containing tabs or newlines are preserved. Renames appear as a deletion and an addition.
• Task validation, evidence freshness, and reviewer approval remain separate from the file inventory.

Validation: ran npm ci --ignore-scripts and the full npm test suite locally with Node 24.21.0. The initial run passed 200 of 202 test commands; the two documentation checks passed on rerun after correcting the wiki release link. Service tests, the strict bridge typecheck, shipping regressions for both installed host layouts, shell syntax, and whitespace checks passed. Source smoke, the Pi smoke check, release-to-install preflight, and the public-summary fixture rendering also passed.

The preview does not stage or commit files. GitHub Actions remains disabled.
