feat: add .implCreate.noseal for bypassing the seal in create

[jo16oh]

A create whose payload always passes the seal still returns the seal's return type:

const SectionId = Val.companion<SectionId>()
  .implCreate(() => randomBytes(4).toString("hex"))
  .implSeal((text, seal): SectionId | undefined =>
    /^[0-9a-f]{8}$/.test(text) ? seal(text) : undefined,
  );

SectionId.create(); // SectionId | undefined, though never undefined

• Add .implCreate.noseal(f), whose create and create.nocopy return the Val
• Reject a function with arguments in .implCreate.noseal at the type level, so no input bypasses the seal
• Skip the custom seal in production; in development, run it and throw if it rejects the created payload or normalization changes it
• Read .implCreate.noseal(f) as the implCreate step in valof-lint; bypassed-companion and unimplemented-trait stopped reading the chain there
• Replace "mint" with "create" or "generate" in JSDoc, error messages and the README
• Add the API row
• Production gzip grows by 44 B, for the wiring of noseal; the development check is removed from production builds
