Merge remote-tracking branch 'origin/record_db_doc_fix' into integration_2026_w16 (!4046)

fix(record_db doc): correct the path for T_messages.txt and mention use of ninja/make

The commit !4038 (51d84419) provided the wrong path for T_messages.txt. The path
it provided holds if the T tracer is built manually using make.

A note to explicitly mention the path for T_messages.txt when T tracer is built
using make.
