Worktree naming: avoid person surnames (scientists/heroes); prefer neutral words like fruits

The auto-generated worktree names in .claude/worktrees/ follow the pattern <adjective>-<scientist-surname>-<hash> (e.g. wizardly-mirzakhani-ce985b).

For users who are not familiar with the names being drawn from (scientists, mathematicians, historical figures, etc.), an unrecognized name appearing in their project folder feels alarming — as if a third party has intruded into the workspace.

Suggestion: switch the surname pool to neutral, universally recognized words such as fruits (apple, mango, papaya, durian, ...). Fruits are language-agnostic, culture-neutral, and never feel like a stranger walking into the repo.

Example before/after:

• before: wizardly-mirzakhani-ce985b
• after: wizardly-mango-ce985b
