feat(cli): harden env checks, add tests, non-interactive flags for new

[marioserrano09]

Closes #95, #96, #97, #98, #99, #100.

Changes

• checkJava() (env.ts): parses the major version out of the version "NN pattern instead of an includes('25') substring match — avoids false positives on e.g. a JDK reporting 17.0.25.
• checkNode() (env.ts): now reads the minimum version from cli.properties via CliConfig instead of a hardcoded 22, matching package.json's engines.node >=24.
• fetchSpringBootVersion() (new.ts): added a 4s AbortSignal timeout so a slow/dead start.spring.io degrades to the fallback instead of stalling the wizard.
• Tests: added vitest (same setup as sdk/ui-core/vue/microfrontend-bridge) with 31 unit tests covering config.ts (properties parsing, token camelCasing, template loading), replace.ts (token replacement, Java package renaming/Application class rename, pom.xml rewriting), env.ts (mocked execa), and the new flag parser. package.json now has a real test script, so pnpm -r test in publish-npm.yml actually gates on this package instead of silently skipping it.
• Non-interactive flags for dynamia new: --name, --scaffold, --backend-lang, --group-id, --artifact-id, --version, --description, --frontend, --pm, --yes, --git/--no-git. Any flag left unset still falls back to its interactive prompt. Verified end-to-end with a real clone of template-backend-java.
• Removed the stray package-lock.json — this is a pnpm workspace and the package was already tracked in the root pnpm-lock.yaml.

Verification

• pnpm run typecheck — clean
• pnpm run build — clean
• pnpm run test — 31/31 passing
• Manual smoke test: dynamia new --name smoke-test --scaffold backend --backend-lang java --group-id com.acme --artifact-id smoke-test --version 1.0.0-SNAPSHOT --yes --no-git generated a correctly renamed project (SmokeTestApplication.java under com/acme/smoke/test).

Note: base branch also depends on #93 (disables the 4 template ids without an existing repo) — that PR is separate and unmerged, this one doesn't touch cli.properties.
