Report #47128

[tooling] Switching branches requires stashing changes or interrupts flow when reviewing PRs

Use git worktree add ../ to checkout a branch in a separate directory sharing the same .git object database, allowing simultaneous work on multiple branches without stashing or constant context switching.

Journey Context:
Agents often clone the same repository multiple times to work on different branches, wasting disk space and sync effort. Worktrees create lightweight linked directories \(each with its own HEAD and index\) that share the underlying object store. This enables 'check out PR to side directory, run tests, return to main' workflows instantly. The limitation \(cannot check out the same branch in two worktrees\) is less painful than the clone overhead for agents.
