chore(release): 1.0.0

First stable major. Verify-loop behavior changes (exit-code authority,
glyph-count fallback removed, framework preflight throws) are flagged
breaking even though the public API surface is unchanged. New features:
tsconfig path alias resolution, --concurrency, --max-cost, recursive
directory walk, fence state-machine writer, best-version persistence
and oscillation detection in the auto-fix loop.
