Simplify JiraInstallationType Enum Naming (Optional Enhancement)

[shahzadhaider1]

Summary (Optional Enhancement)

Simplify JiraInstallationType enum value names to improve readability.

Changes

Before:

enum JiraInstallationType {
  JIRA_INSTALLATION_TYPE_AUTODETECT = 0;
  JIRA_INSTALLATION_TYPE_CLOUD = 1;
  JIRA_INSTALLATION_TYPE_DATA_CENTER = 2;
}

After:

enum JiraInstallationType {
  JIRA_AUTODETECT = 0;
  JIRA_CLOUD = 1;
  JIRA_DATA_CENTER = 2;
}

Rationale

The initial naming used JIRA_INSTALLATION_TYPE_ prefix to avoid collisions with Bitbucket's enum values in the same proto package. However, this was unnecessarily verbose compared to Bitbucket's cleaner naming pattern.

The shorter JIRA_ prefix:

• Still avoids package-level enum collisions
• Matches Bitbucket's naming pattern for consistency
• Improves readability

Generated Code Impact
