[deep-report] Extend envutil with GetBoolFromEnv/GetStringFromEnv and migrate os.Getenv("CI") bypasses

[github-actions]

Description

The pkg/envutil package was created to centralise env-var access but exposes only GetIntFromEnv. Boolean flags (CI, GO_TEST_MODE, CODESPACES) and token-presence checks are still read via raw os.Getenv, and IsRunningInCI() in pkg/cli is bypassed by 3 same-package callsites. Add GetBoolFromEnv and GetStringFromEnv helpers (with spec tests + README, mirroring GetIntFromEnv), then migrate the 3 os.Getenv("CI") bypasses to call IsRunningInCI().

Expected Impact

Consistent, mockable env-var behaviour across environments; unblocks the stalled osgetenvlibrary migration.
