Bug: entire v0.4.5 corrupts local git config `user.name` by setting it to the literal string "user.email"

[jojoprison]

Description

After entire creates checkpoint commits or merges session logs, .git/config gets user.name = user.email (the literal string "user.email") instead of the actual username. This causes all subsequent commits in the repository to show an incorrect author.

Environment

• entire version: 0.4.5 (a92c0d0)
• OS/Arch: darwin/arm64
• Go version: go1.25.6
• Install method: Homebrew (entireio/homebrew-tap)

Evidence

• After entire performs "Merge remote session logs" or creates checkpoint commits, .git/config contains:

  [user]
      name = user.email

• The global git config has user.name = jojoprison and user.email = egyabig2@gmail.com, but the local override created by entire sets user.name to the literal string "user.email" — clearly a variable name reference bug in the code.
• Running strings $(which entire) reveals the string temporaryuser.name in the binary, which suggests a string concatenation or template bug where a variable like temporary + user.name was intended but user.email was used instead.
• 72 commits were affected — all showing author as user.email <egyabig2@gmail.com> instead of jojoprison <egyabig2@gmail.com>, starting from when entire performed its first "Merge remote session logs" operation.

Steps to Reproduce

1. Set global git config: git config --global user.name "jojoprison" and git config --global user.email "egyabig2@gmail.com"
2. Use entire.dev with Claude Code sessions in a repository
3. Let entire create checkpoint commits or merge session logs
4. Check local git config: git config --local user.name
5. Actual result: user.email (literal string)
6. Expected result: Either no local override, or the actual username (jojoprison)

Impact

• All commits made after entire's operation show wrong author name
• This silently corrupts the git history — users may not notice for a long time
• In our case, 72 commits had to be identified as affected

Workaround

Remove the corrupted local config entry:

git config --local --unset user.name

Root Cause Hypothesis

Looking at the binary strings, it appears there's a bug where entire tries to set a temporary user.name in the local git config but accidentally writes the literal string "user.email" instead of reading the value from git config user.name or git config user.email. This could be a typo in the Go source code, e.g.:

// Likely bug: something like
git config --local user.name "user.email"  // writes literal "user.email"
// Instead of:
git config --local user.name "$actual_username"
