refactor(cli): rename "trace id" to "correlation id"

[matthewvolk]

What/Why?

Renames all references to "Trace ID" in the Native Hosting CLI to "Correlation ID" for consistency with the X-Correlation-Id HTTP header already used in API requests.

Changes span both @bigcommerce/catalyst and create-catalyst:

• Rename sessionId property to correlationId in both Telemetry classes
• Update user-facing error output ("Trace ID" → "Correlation ID")
• Update Segment event property name (sessionId → correlationId)
• Update tests and in-repo documentation (CHANGELOG, changeset)

Discussion point: The Jira ticket scopes this to the "Native Hosting CLI" (@bigcommerce/catalyst), but this PR also renames sessionId → correlationId in create-catalyst's Telemetry class for consistency. If the team considers that out of scope, those changes can be reverted — let me know.

Internal docs update for bigcommerce/documentation is in a separate PR: https://github.com/bigcommerce/documentation/pull/2370

Testing

• All 126 existing tests pass (pnpm --filter @bigcommerce/catalyst test)
• Grepped both packages for any remaining sessionId or Trace ID references — none found
• X-Correlation-Id HTTP header name is unchanged

Migration

No migration needed. This is a rename of internal property names and user-facing strings only.
