zsh: escape double-quoted values

Browse Source 
The zsh value renderer emits strings in double quotes so session variables can still expand references such as $HOME. Embedded quotes, backslashes, and backticks were not escaped, which could corrupt generated zsh code or trigger command substitution.

Escape those double-quote-sensitive characters while preserving dollar expansion for existing session-variable semantics.
