@ngxson Cherry picked in #18675 and removed the workaround, can confirm it works correctly on all templates that in fact have tool definitions (found that Apertus had an incorrect macro for rendering tools, after correcting to OpenAI-compatible format it works as well).

… and new jinja template engine (ggml-org#1369)

common : add nemotron 3 parsing (ggml-org#18077)

common : add parser for ministral/mistral large 3/devstral 2 (ggml-org#17713)

common : default content to an empty string (ggml-org#18485)

chat: make tool description and parameters optional per OpenAI spec (ggml-org#18478)

Per the OpenAI API specification, both 'description' and 'parameters'
fields in tool function definitions are optional. Previously, the parser
would throw an exception if these fields were missing.

jinja : implement mixed type object keys (ggml-org#18955)

---------

Co-authored-by: Xuan Son Nguyen <son@huggingface.co>

jinja : undefined should be treated as sequence/iterable (return string/array) by filters/tests (ggml-org#19147)

`tojson` is not a supported `undefined` filter

keep it DRY and fix some types

jinja : do not pass empty tools and add some none filters (ggml-org#19176)

jinja : add unordered_map include to value.h [no ci] (ggml-org#19205)

jinja : add missing 'in' test to template engine (ggml-org#19004) (ggml-org#19239)

The jinja template parser was missing the 'in' test from
global_builtins(), causing templates using reject("in", ...),
select("in", ...), or 'x is in(y)' to fail with
"selectattr: unknown test 'in'".

This broke tool-calling for Qwen3-Coder and any other model
whose chat template uses the 'in' test.

Added test_is_in supporting array, string, and object containment
checks, mirroring the existing 'in' operator logic in runtime.cpp.

Includes test cases for all three containment types plus
reject/select filter usage.

chat: fix case where template accepts type content only (ggml-org#19419)

mtmd : chat : Fix extra \n between text and media marker (ggml-org#19595)

Thanks to @tugot17 for detecting and reporting the issue.

For vision models (e.g. LFM2.5-VL-1.6B and Qwen/Qwen3-VL-4B-Instruct) `llama-mtmd-cli` produces identical output to HF implementation.

However `llama-server` doesn't. I traced it down to extra newline
inserted after `<__media__>`.

This happens in `to_json_oaicompat`, that treats media markers as text
and joins all parts with `\n` separator.

PR introduces new type `media_marker` and uses it for media markers.
Extra logic is added to prevent insertion of newlines before and after
media markers.

With this change number of input tokens is identical to HF
implementation and as a result the output is also identical.

I explored other ways to address the issue
* remove completely `\n` between text parts in `to_json_oaicompat`
* merge text messages in server-common.cpp before sending them to `to_json_oaicompat`

Please propose alternative ways of fixing this issue.
