Port the ZAP capability layer to TypeScript at src/cap.ts, the byte-for-byte peer of github.com/zap-proto/go/cap (SPEC.md §2.3/§3/§4 + capabilities_kinds.md). Exported at @zap-proto/zap/cap; the universal root stays browser-safe. - Cap view/builder over the zero-copy runtime for capabilities.zap (v1.1, 3408B Sig footer); Capability/Caveat/Revocation codec vendored in, as Go vendors capabilities_zap.go into package cap. - canonicalBytes: Capability[0..164) || canonical(Caveats) — byte-identical to Go's signed scope; heap-indirection excluded so it is identical across runtimes. - issue + attenuate: mint-time delegation gate (parent PermAttenuate or Kind==Delegate), monotonic perm narrowing, holder→issuer linkage, expiry shrink-only. Signs canonicalBytes. - verify + verifyChain: all SPEC §2.3 invariants (monotonic perms, holder linkage, target invariance, root zero-Parent, delegation gate) + FAIL-CLOSED scheme dispatch (reject 0x00/unknown; never downgrade; never return ok on an unverified sig). - capId = SHA-256(canonicalBytes || Sig) (spec-corrected from BLAKE3). - Schemes: Ed25519 MANDATORY via node:crypto (synchronous, RFC 8032, raw seed framed into PKCS8/SPKI). ML-DSA-65 / hybrid / secp256k1 fail-closed unless a schemeVerify hook is wired — the JS runtime fabricates no PQ verify. - Zero npm runtime deps preserved (node:crypto is stdlib); synchronous API matching Go exactly, no async contagion through the auth primitive. Cross-language KAT (interop proof): test/cap_go_kat.hex is a Go-signed cap over a fixed Ed25519 seed (32x0x42); test/cap_kat.test.ts decodes it, asserts JS canonicalBytes + capId match Go's, verifies the Go Ed25519 sig in JS -> true, and a tampered variant -> false. Re-issuing the same inputs+seed in JS reproduces Go's exact CapID (1b809edc...), signature, and full wire bytes. Tests: 110 pass (66 pre-existing + 44 new mirroring Go's 34 cap tests: happy/attenuate-refuses/chain-rejects/fail-closed/revocation + KAT + custom Signer). Bump @zap-proto/zap 1.4.2 -> 1.5.0.
