Could we add source file name and line number to log output?

Problem When we are reading logs while debugging an issue, i personally feel it is highly useful to see line number and the source file name in logs. Currently a typical log output looks like:

2026-08-31T07:22:10.398376Z  INFO HTTP request{method=PUT host="localhost:7700" route=/indexes/test-debug/settings/stop-words query_parameters= user_agent=curl/8.18.0 status_code=202}: meilisearch: close time.busy=10.0ms time.idle=5.50ms
2026-08-31T07:22:11.392857Z  INFO index_scheduler::scheduler: A batch of tasks was successfully completed with 1 successful tasks and 0 failed tasks.

2026-08-31T07:22:37.235039Z  INFO milli::update::new::indexer::guess_primary_key: Primary key was not specified in index. Inferred to 'id'
2026-08-31T07:23:06.690697Z  INFO index_scheduler::scheduler::process_index_operation: document indexing done indexing_result=DocumentAdditionResult { indexed_documents: 31944, number_of_documents: 31944 } processed_in=29.457108427s
2026-08-31T07:23:07.066684Z  INFO index_scheduler::scheduler: A batch of tasks was successfully completed with 1 successful tasks and 0 failed tasks.

It is hard to find the log message in the code with just mod/fn name.

Could be a good-first-issue

Expected behavior Include the file and line:

2026-08-31T07:27:07.286467Z  INFO HTTP request{method=POST host="localhost:7700" route=/indexes/movies100/documents query_parameters= user_agent=curl/8.18.0 status_code=202}: meilisearch: crates/meilisearch/src/lib.rs:188: close time.busy=19.8ms time.idle=1.41s
