fix: setup pre-release channel releases

[dylantientcheu]

Summary

• Adds prerelease-aware publishing behavior: npm prerelease versions publish under their channel dist-tag, and Chocolatey publishing is skipped for prerelease tags.
• Adds a manual Create release tag workflow that computes and pushes release tags for fix, minor, major, prerelease, and freeform releases while keeping the existing tag-triggered GoReleaser workflow as the publisher.
• Adds release guardrails: exact confirmation for major releases, dry-run support, remote/local duplicate tag checks, release-token tag pushes, and docs PR skipping for prerelease tags.

Test plan

• bash -n scripts/create-release-tag.sh && bash -n scripts/npm-publish.sh
• ruby -e 'require "yaml"; YAML.load_file(".github/workflows/create-release-tag.yml"); YAML.load_file(".github/workflows/releases.yml"); puts "workflow yaml parsed"'
• git diff --check
• Dry-ran scripts/create-release-tag.sh for fix, minor, major without confirmation, major with confirmation, beta prerelease, alpha prerelease, and freeform release.
