Follows #1790, which quoted the values written by tomlparser.rb. The same unquoted interpolation remains in two other parsers and in setGlobalEnvVar, so a value is subject to shell processing when the generated file is sourced rather than arriving as configured: quotes truncate it, a bare $ is substituted away, and surrounding whitespace is dropped. Reuses the get_command_linux helper introduced by #1790, defined locally in each parser to match how get_command_windows is already handled across the tree: - tomlparser-common-agent-config.rb and tomlparser-metric-collection-config.rb - setGlobalEnvVar, which re-emitted values into /opt/env_vars using double quotes, leaving them open to the same processing when that file is sourced Behaviour is unchanged for well-formed configuration. Across every affected setting and value shape, the variable bash ends up with after sourcing is identical to before, for both the shipped defaults and a fully populated config. The Windows KEY=VALUE writes are untouched, since those are split on '=' and must not carry quotes. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
