Align structural reading evidence labels

[flyingrobots]

Summary

• Adds the Slice 1 design packet for structural-history evidence label alignment.
• Extends StructuralReadingPort evidence with the Graft taxonomy: echo-native, git-warp-imported, and fallback-translated.
• Maps those Graft labels to the Wesley-generated StructuralEvidenceKind values.
• Labels current git-warp structural-reading adapter evidence as fallback-translated while keeping nativeContinuumWitness: false.
• Hardens structural evidence guards so malformed translated-substrate evidence cannot masquerade as Echo-native evidence.
• Updates focused structural-reading tests, Graft publishing instructions, and the changelog.

Why

This is the first Graft-only pre-Echo slice after PR #63. The goal is to make evidence provenance explicit before runtime migration so current git-warp readings cannot be mistaken for future Echo-native evidence.

Validation

• RED: pnpm exec vitest run test/unit/ports/structural-reading.test.ts failed on the malformed translated-substrate masquerade regression before the guard fix.
• GREEN/VERIFY: pnpm exec vitest run test/unit/ports/structural-reading.test.ts test/unit/warp/structural-reading-adapter.test.ts passed 2 files / 8 tests.
• pnpm lint passed.
• pnpm typecheck passed.
• pnpm test passed 224 files / 1639 tests.

@codex Self-audit finding for PR #64.

Severity	File	Lines	Issue	Evidence	Recommended mitigation
P2	src/ports/structural-reading.ts	149-158	Echo-native guard trusts evidenceLabel alone	isContinuumNativeEvidence and isEchoNativeEvidence return true when evidence.evidenceLabel === "echo-native". A malformed translated-substrate object carrying that label could pass the guard, which weakens the slice invariant that current git-warp evidence cannot masquerade as Echo-native witnesshood.	Add a regression test with a malformed translated-substrate object carrying echo-native; then make Echo-native guards require kind === "continuum-native", evidenceLabel === "echo-native", and nativeContinuumWitness === true. Tighten imported/fallback helpers to require translated-substrate shape and nativeContinuumWitness === false.
