Move all the CI detection logic into one place (used to be in 3), add a couple more CI providers to the detection list.

📌 Commit 0501b8b

This PR consolidates CI detection in the CDK CLI toolchain: it relocates ci-systems.ts into @aws-cdk/toolkit-lib, adds a single unified isCI() there, removes the two duplicate isCI() definitions (in lib/cli/util/ci.ts and shell-env.ts), re-exports the symbols to the CLI through api-private, and repoints every consumer. It also adds four CI providers (Bamboo, BuildKite, Travis, Heroku) to the detection table. The only substantive logic change is that the unified isCI() now falls back to detectCiSystem() when CI is unset, generalizing a pattern already present in the telemetry path; the relocated symbols stay internal and are not added to the toolkit-lib public API. The refactor is clean and consistent with the repo's layering. One minor doc-accuracy nit on the isCI prop comment is noted inline.

This also changes the behavior of the ci detection such that now we will automatically do --ci behavior if a ci env var is detected, whereas before the detection only impacted telemetry.

could you clarify if this is the intent of the PR?
