Add deno task release

Copy// scripts/release.ts

const denoJson = JSON.parse(Deno.readTextFileSync(denoJsonPath));
const currentVersion = denoJson.version;

    Deno.exit(1);
  }
  newVersion = input;
}

if (newVersion.startsWith("v")) {
  newVersion = newVersion.substring(1);
}

// Update deno.json
denoJson.version = newVersion;
Deno.writeTextFileSync(
  denoJsonPath,
  JSON.stringify(denoJson, null, 2) + "\n",
);
console.log(`Updated deno.json version to ${newVersion}`);

// Run git commands
async function run(cmd: string[]) {
  console.log(`> ${cmd.join(" ")}`);
  const command = new Deno.Command(cmd[0], {
    args: cmd.slice(1),
    stdout: "inherit",

  });
  const { code } = await command.output();
  if (code !== 0) {
    console.error(`Command failed with code ${code}`);
    Deno.exit(code);
  }
}

await run(["git", "add", "deno.json"]);
await run(["git", "commit", "-m", `chore: bump version to ${newVersion}`]);

console.log(
  `\nSuccessfully bumped version to ${newVersion}. Please push to trigger release workflow.`,
