Optionally strip PROPERTIES when sending requests from Org mode buffers?

[weavermarquez]

As indicated in the dry runs, the system message is included twice when querying from a gptel buffer turned org file.

Expected behaviour:

The gptel :PROPERTIES: values, especially GPTEL_SYSTEM, should not be included in the user prompt.

Replication Steps:

0. Ensure gptel--system-message is set.
1. Create a chatbot temporary buffer e.g. *Claude*
2. Save it as an org file; this will create a PROPERTIES drawer.
3. Run interactive gptel-menu, Dry Run > Inspect query (Lisp) [1] or (JSON) [2]

The system message is not being sent twice, as you can see from the :system parameter of the request. gptel sends the buffer contents as-is, which includes the system message since it's been written to the buffer.

So the question is if all :PROPERTIES: blocks should be stripped when constructing the user prompt. See prior discussion in #141 (specifically this comment and my response) and one possible workaround based on #325.
