configure C3 experimental projects to use @cloudflare/autoconfig directly

[dario-piotrowicz]

C3 for frameworks in experimental mode right now spawns a wrangler setup process. This is not super efficient and it also ties C3 to Wrangler which is not ideal (given cf and all).

So in this PR I am updating C3 to use the autoconfig package directly instead.

I've completed my analysis. The change is well-structured. The main behavioral observations:

1. Wrangler not installed when project already configured: The old code always ran installWrangler() for the experimental path. The new code only installs Wrangler (via autoconfig) when !details.configured. For fresh C3 scaffolds this is essentially always non-configured, so this is unlikely to matter in practice — but it's a real behavioral difference worth noting.

2. The stringifyLogArgs, dialog mappings, and metrics wiring are all correct. All deps are declared.

These are minor/low-severity observations, not concrete bugs with a clear fix that I should provide as a suggestion. The Wrangler-install-on-configured difference is a design judgement (a fresh scaffold is never pre-configured), and I shouldn't post a speculative suggestion that changes behavior without certainty. Nothing else rises to actionable severity per the guidelines (no logic bugs, security issues, backward-compat violations, or incorrect API behavior in the actual usage path).
