Provide installation paths for local packs in `.cbuild-run.yml`

[TeoMahnic]

Describe The Problem To Be Solved
.cbuild-run.yml does not include pack installation path information. When local packs are used, their locations can not be derived reliably, as they are not covered by CMSIS_PACK_ROOT. This prevents tools and debuggers from resolving character access sequences (e.g. $S) and can lead to failures in flash and debug workflows.

Suggest A Solution
Extend .cbuild-run.yml to include explicit installation paths for local packs, similar to the packs: node in .cbuild.yml
