[SDK-767] Release 0.3.0

[devtools-agent]

Description of the change

Bumps the package version from 0.2.1 to 0.3.0 in package.json and package-lock.json. Version-only, following the 0.2.0 release PR (#13).

Changes since v0.2.1:

• Upgraded axios to 1.x, then to 1.20.0, closing known vulnerabilities (Upgrade Axios to v1 #25, [SDK-732] Fix --next uploads over 10 MB (#14) and bump axios to 1.20.0 (#23) #33)
• Fixed --next uploads failing over 10MB ([SDK-732] Fix --next uploads over 10 MB (#14) and bump axios to 1.20.0 (#23) #33)
• Bumped adm-zip to clear high-severity alerts ([SDK-731] Bump axios and adm-zip, fix missing CI #31)
• Added .npmrc with ignore-scripts=true to block dependency install hooks (Add .npmrc ignore-scripts=true (Miasma install-hook mitigation) #29)
• Switched npm publishing to trusted publishing ([SDK-720] Publish to npm with trusted publishing #32)

No breaking API change, so this is a minor bump.

After merge: tag v0.3.0 and publish a GitHub Release. publish.yml publishes to npm when the release is published, and it checks that the tag matches package.json. This PR doesn't tag, release, or publish anything.

Release 0.3.0 version bump

This PR only changes the version from 0.2.1 to 0.3.0, in package.json and in the two root version fields of package-lock.json.

• Manifest and lockfile agree: package.json:3, package-lock.json:3 and package-lock.json:9 all read 0.3.0, so npm ci will not report a mismatch.
• Old version not left anywhere: no other file in the repo (outside node_modules) contains 0.2.1. The CLI's --version output comes from yargs rather than a hardcoded string.
• Follows the repo's own rule: AGENTS.md:5 says version bumps go in their own PR, and this PR changes nothing else.
• Release tag: .github/workflows/publish.yml:37-41 stops the publish unless package.json's version matches the GitHub release tag with any leading v removed. Tag the release v0.3.0 (or 0.3.0). Because the version has no pre-release suffix, it will be published under the latest dist-tag (publish.yml:42-45).

I couldn't see the commit history in this read-only checkout, so I didn't check whether a minor bump (rather than a patch) fits the changes since 0.2.1. The author should confirm that. No defects found.
