[deploy-helpers] Extract Worker startup profiling from Wrangler

[petebacondarwin]

Prerequisite for https://github.com/cloudflare/cf/issues/97.

Summary

Wrangler's startup profiler was private to check startup, so cf could not implement the equivalent command without importing Wrangler internals. This exposes the generic implementation from @cloudflare/deploy-helpers/startup-profile.

• Share Worker upload parsing, bundle sizing, CPU profiling, and profile summaries.
• Make deploy startup-limit diagnostics lazy-load the shared profiler.
• Migrate wrangler check startup, deploy, Pages deploy, and version upload away from Wrangler callback injection.
• Preserve analyseBundle as an optional deprecated compatibility callback.
• Harden the inspector lifecycle with command acknowledgements, response correlation, a timeout, and guaranteed cleanup.
• Add the Wrangler build alias and a minor changeset for the new public subpath and deprecation.

Validation

• pnpm --filter @cloudflare/deploy-helpers build
• pnpm --filter @cloudflare/deploy-helpers check:type
• pnpm --filter @cloudflare/deploy-helpers type:tests
• pnpm --filter @cloudflare/deploy-helpers test:ci — 141 tests
• pnpm --filter wrangler build
• pnpm --filter wrangler check:type
• Focused Wrangler startup, validator, and deploy suites — 52 tests
• Focused type-aware lint, formatting, package dependency validation, and git diff --check

---

• Tests
  • Tests included/updated
  • Automated tests not possible - manual testing has been completed as follows:
  • Additional testing not necessary because:
• Public documentation
  • Cloudflare docs PR(s):
  • Documentation not necessary because: this shares an internal implementation without adding a new Wrangler command or option.
