fix(jsonc): edit comma correctness — multi-del + trailing commas (#50)

* fixes a bug with multiple successive del() ops

* fix(jsonc): never manufacture an invalid trailing comma on edit

Appending a new last key/element to a multi-line JSON object/array stamped
a comma after it, and deleting the last object member left the previous
member's separator comma dangling before `}`. Both produce invalid strict
JSON; JSON5/JSONC tolerate trailing commas, so edikt's own lenient reader
round-tripped the damage and it stayed hidden until a strict consumer
(Claude Desktop, serde_json, python json) rejected the file.

Fix, format-preserving: the last appended element only gets a trailing
comma when the container was already trailing-comma style; deleting a last
member with no comma of its own strips the previous member's now-dangling
comma (mirroring delete_element for arrays). A container that already uses
trailing commas keeps that style. Adds tests for both bugs and both
preservation cases, asserting exact bytes (stronger than the lenient parser
that hid the bug).

* release: bump edikt-jsonc and edikt to 0.2.2 (trailing-comma fix)

Patch bump for the JSONC edit comma-correctness fix: edikt-jsonc 0.2.1 ->
0.2.2, the edikt binary 0.2.1 -> 0.2.2, and the workspace dep pointer to
match so the published binary requires the fixed crate.
