# DEVX-157: Add role defaults path to create_dependency_pr search

## Problem
`create_dependency_pr` only searches `pyproject.toml` and `ansible/group_vars/all/images.yml` for pinned versions. The sso-bridge role pins its version in `ansible/roles/sso_bridge/defaults/main.yml` via `sso_bridge_version: "0.1.0"`, which is not searched.

## Approach
Add `ansible/roles/sso_bridge/defaults/main.yml` to the search paths.

REQ-1: Add ROLE_DEFAULTS_PATH constant pointing to ansible/roles/sso_bridge/defaults/main.yml
REQ-2: Include ROLE_DEFAULTS_PATH in the search loop

## Test Plan
- Verify existing tests pass
- Verify find_pinned_version finds sso_bridge_version in the defaults file

## Deploy Plan
- Merge to master, auto-release new devx version

## Rollback Plan
- Revert the merge commit

## Acceptance Criteria
- [x] REQ-1: ROLE_DEFAULTS_PATH constant added
- [x] REQ-2: search loop includes ROLE_DEFAULTS_PATH
