Fix shutdown ownership across persistent, one-shot, and prepended host handlers before and after initialization. Delegation remains stable during asynchronous host cleanup until reinitialization.

Adds default field/key redaction, generic fatal diagnostics, validated immutable hook output, correctly budgeted Retry-After handling (including dates and overflowing integers), and separate event fingerprint namespaces.

Verified current head 8b74d0d:

• 39 tests pass on Linux Node 22/24/26 and Windows Node 24.
• Clean-consumer HTTP/redaction/declaration checks pass; runtime dependencies remain zero.
• 789 handwritten code lines, including tests and verification scripts.
• Full reachable-history Gitleaks scan reports no leaks; CodeQL security-extended reports zero findings; npm advisory checks report zero known vulnerabilities; all three development packages have verified registry signatures.
• Remote contents match all 31 reviewed text files. CI retains the verified npm tarball.

CI: https://github.com/garvj65/tinytrace/actions/runs/39464453402

Prepares version 1.0.0 and an exact-commit gated npm release with provenance and registry-integrity verification. Publishing is attempted only after trusted merged-main CI succeeds; npm account/scope authentication may still require setup. Privacy matching and in-memory delivery have explicit documented limits; passing checks are not a guarantee that every possible defect is absent.
