Bug fixes - 4.64.3

• A set_env written as a list of tables in TOML now keeps every file entry and honors the order of the entries, so merging one environment's set_env into another no longer drops the environment file it referenced (:issue:4093) - by :user:Rodrigo-Palma.

  • Each { file = "..." } entry is read; previously only the last one survived, because the entries were merged into a single table first and a table cannot hold the key twice.
  • A variable set after a file entry wins over the value the file provides, matching the file| form in INI; previously a repeated variable was pulled back to its first position, letting the file override it.
  • A later entry that sets a variable without a marker clears the marker an earlier entry gave it, again matching the INI form. (:issue:4093)

• Create the package build environment change_dir directory before running the build commands, as the documentation already promises. (:issue:4095)
