Update CHANGELOG.md

* Harden remote func bootstrapping

Replace bare `source <(curl ...)` calls with a `_bootstrap_source` helper that validates both the download exit code and the presence of a probe function after sourcing. This prevents silent failures when DNS is not yet available in a freshly booted container or when a download fails mid-stream. Applies to build.func, install.func, and alpine-install.func. Also adds retry flags and a connect timeout to curl/wget.

* Refactor bootstrap error handling with helper

Extract repeated fatal-error logic into a `_bootstrap_die` helper across alpine-install.func, build.func, and install.func. The helper uses `msg_error` when available, falling back to stderr, then exits with code 115. Inline error blocks are replaced with cleaner one-liner `|| _bootstrap_die` calls.
