[p3n1cillin]

Staged for upstream. Open it on boykopovar/AnyPS5 only after the PRs ahead of it are merged or closed (one open PR per author until one is merged).

What

Implements sce::Json::Object::insert(const Pair&), which PPSA30601 imports (its TechnicalDebt entry listed it among six members declared without parameters).

• The mangled name does not encode a return type, which is why feat(libSceJson2): implement Array::iterator assignment, postfix increment and Object::Pair boykopovar/AnyPS5#4476 leaves insert as a stub. The PS Vita sce::Json declaration in vitasdk gives it: iterator insert(const Pair& p), returning an iterator to the inserted pair. The iterator is returned through the hidden result pointer, like Object::begin, end and find here.
• The pair is copied to the end of the object, so iteration and serialization keep insertion order, as operator[] does.
• Inserting a key the object already has throws, because whether the console replaces, keeps or duplicates the pair is unknown. A null pair throws.
• TechnicalDebt gets an entry for insert, and the PPSA30601 entry now lists five remaining members.
• guest_json covers the returned iterator, the copy being independent of the caller's pair, insertion order in serialization, and the duplicate-key throw leaving the object unchanged.

Progress: libSceJson2 104/116 → 105/116.

Overlap: boykopovar#4476 replaces the neighbouring Object::Pair and Array::iterator stubs in the same file and edits the same PPSA30601 TechnicalDebt line. Whichever merges second needs a trivial rebase. Neither depends on the other.

Tested

Linux (Ubuntu 24.04, GCC 13.3), BUILD_TESTING=ON: guest_json passes. Removing the duplicate-key check makes it fail. python3 tools/check_conventions.py --base origin/main passes. No title tested.

Checklist

• Based on current main; no other open PR implements the same functions

• No comments in code except technical debt
• Unimplemented paths throw (NotImplemented_nid_no_patch); silent stubs are listed in TechnicalDebt
• No notes, investigation .md files or images added to the repository (attach them to this PR)
• New third-party code is a submodule built from source
• Generic behaviour, not specific to one title
• Depends on: none
• Unblocks: none
