Summary

Adds a new gitlens.defaultCurrentUserNameStyle setting to control how the current git user is identified across blame annotations, hovers, CodeLens, the Commit Graph, and other UI elements. Options include "You" (default, preserving current behavior), the user's real name from git config, or "Name (you)".

Impact

Addresses longstanding user requests to see their real name instead of "You" — useful for screenshots, pair programming, and consistency.

Resolves #1230, resolves #4136, resolves #4745.

Validation

• Set gitlens.defaultCurrentUserNameStyle to you, name, and nameAndYou in turn
• Verify blame annotations, hovers, CodeLens, status bar, Commit Graph, commit details, and the rebase editor all reflect the chosen style
• Confirm the default (you) preserves existing behavior

Risk

• UI elements that previously showed "You" unconditionally now depend on a setting — verify no regressions in edge cases (uncommitted changes, stashes, Live Share)
