[Code Quality] Merge overlapping PRInfo and PullRequest structs in pkg/cli into a single PullRequest type

[github-actions]

Description

pkg/cli has two separate structs representing a GitHub pull request fetched via gh pr view, with non-overlapping fields:

• PRInfo (pkg/cli/pr_command.go:28): Number, Title, Body, State, HeadSHA, BaseBranch, HeadBranch, SourceRepo, TargetRepo, AuthorLogin
• PullRequest (pkg/cli/pr_automerge.go:21): Number, Title, IsDraft, Mergeable, CreatedAt, UpdatedAt

Both represent the same GitHub entity in the same package, causing confusion about which type to use and duplicated fetch/parse logic.

Suggested Changes

• Define a single PullRequest struct in pkg/cli containing the union of fields both call sites need
• Update pr_command.go and pr_automerge.go to use the unified type
• Update any gh pr view --json field lists to fetch the union of needed fields in one place
• Remove the now-redundant PRInfo type once all call sites are migrated

Files Affected

• pkg/cli/pr_command.go
• pkg/cli/pr_automerge.go

Success Criteria

• Only one PR-representation struct exists in pkg/cli
• All existing PR command and automerge tests pass
• No loss of fields/functionality at either call site

Priority

Medium - reduces confusing duplication of core domain type; effort ~2-3 hours
