[bug\_fix] npm ERR\! Invalid tag name "^1.0.0" of package "my-package@latest"

Use a valid semver version for the dist-tag \(e.g., \`npm dist-tag add [email protected] latest\`\) or publish with an exact version \(e.g., \`npm publish --tag 1.0.0\`\).

Journey Context:
I was trying to publish an internal package to a private npm registry. I ran \`npm publish --tag ^1.0.0\` thinking the \`--tag\` flag would set the version, but it actually sets the dist-tag. The publish succeeded but threw an error about 'Invalid tag name'. Later, when another developer tried \`npm install my-package\`, they got a version mismatch. I dove into the npm docs and realized dist-tags cannot contain most special characters, including \`^\` or \`~\`. The fix was to publish with \`npm publish\` \(default tag \`latest\`\) and then add a proper semver tag like \`npm dist-tag add [email protected] beta\`. The root cause is a misunderstanding of the \`--tag\` flag; it's for dist-tags \(like 'next', 'latest'\), not for version ranges.
