Task: Implement the Desktop Entry Reader feature

TASK-DESCRIPTION

Create: sources/desktop/desktop_entry_reader.h
Create: sources/desktop/desktop_entry_reader.cpp
Create: dataflow.in/desktop/spec-example.desktop
Create: dataflow.in/desktop/localized.desktop
Create: tests/11-desktop-entry-reader.sh The reader parses the *.desktop format into ordered groups, keys, and values, and implements the requirements in prompts/features/04-desktop-entry-reader.md. The specification example and the localized sample are the fixtures the portable test reads.

TASK-OUTPUT

Produce these complete files in this order, then the VERIFICATION: line: 1. sources/desktop/desktop_entry_reader.h 2. sources/desktop/desktop_entry_reader.cpp 3. dataflow.in/desktop/spec-example.desktop 4. dataflow.in/desktop/localized.desktop 5. tests/11-desktop-entry-reader.sh

TASK-CONTEXT

Format facts are in documents/08-desktop-entry-format.md; the language conventions are in prompts/flavors/02-cpp-conventions.md and the naming conventions in prompts/flavors/01-semantic-sort-naming.md. The parser is a library with no dependency on the rest of the project.
