feat(analyze): add shared runtime target resolution

[dreyfus92]

this PR adds the shared runtime target plumbing: there’s a small resolver that reads --browserslist-query / --runtime, falls back to project Browserslist then engines.node, and sticks the result on AnalysisContext for later use. The actual checks (core-js, replacements, etc.) still behave like before we’re not switching them over yet.

we also surface the resolved target in the analyze summary (and JSON stats) so it’s obvious what the run thought the target was, added browserslist as a real dependency, and covered the resolver with a few tests.

Note

also for some reason we had a duplicated fast-wrap-ansi and I removed it.
