fix: promote cmd should sync app-interface first before making change

[feichashao]

Code changes assisted by Claude Code. Reviewed and validated by human.

Problem

When I use the promote saas command, it failed to create a commit.

osdctl promote saas --serviceName saas-xxxx-xxxx --osd --gitHash xxxxx

Error while promoting service: failed to commit changes to app-interface; manual commit may still succeed: failed to commit changes: command failed: exit status 1

The issue was,

• osdctl reads the current git hash in the current branch.

Current Git Hash: 58384043156bf396ea76e7c6101c0f002145dd57

• Then, osdctl tries to replace the currently hash in the master branch with the new hash. However, the master branch is out of sync with the upstream branch.
• My environment also has another corner case. The master branch is not tracking the origin/master.

Changes

• This PR makes the promote command to sync and use the latest origin/master before reading and replacing the git hash.

Aspect	BEFORE	AFTER
Sync with remote	❌ Never syncs	✅ Syncs at the very beginning
When sync happens	N/A	Before reading any files
What gets synced	N/A	git reset --hard origin/master
File read source	Local master (could be outdated)	origin/master (always up-to-date)
currentGitHash	Could be wrong if master outdated	Always correct
String replacement	Could fail if hashes mismatch	Always works
Promotion baseline	Unpredictable	Always from origin/master
User experience	Must remember to git pull first	Automatic sync
