postCreate hooks silently stop if a hook reads from stdin

[acevif]

Bug

If a postCreate hook runs a command that reads from stdin, all subsequent hooks are silently skipped.

Root cause

run_hooks iterates over hooks using a heredoc:

while IFS= read -r hook; do
  ( eval "$hook" )   # subshell inherits stdin = the heredoc
done <<EOF
$hooks
EOF

Each hook's subshell inherits the parent's stdin, which is the heredoc itself. A command that reads stdin drains the remaining lines, so subsequent read -r hook calls get nothing and the loop exits early.

Minimal reproduction

.gtrconfig:

[hooks]
    postCreate = "echo 'hook 1: before stdin read'"
    postCreate = "cat"
    postCreate = "echo 'hook 3: this should run but does not'"

Output of gtr new test-branch:

[OK] Hook 1: echo 'hook 1: before stdin read'
hook 1: before stdin read
[OK] Hook 1 completed successfully
[OK] Hook 2: cat
echo 'hook 3: this should run but does not'
[OK] Hook 2 completed successfully

[OK] Worktree created: ...

Hook 3 never runs. Its command text is visibly consumed and printed by cat.

Suggested fix

https://github.com/coderabbitai/git-worktree-runner/blob/v2.6.0/lib/hooks.sh#L35-L44

Before:

    # Run hook in subshell with properly quoted environment exports
    if (
      # Export each KEY=VALUE exactly as passed, safely quoted
      for kv in "${envs[@]}"; do
        # shellcheck disable=SC2163
        export "$kv"
      done
      # Execute the hook
      eval "$hook"
    ); then

After:

    # Run hook in subshell with properly quoted environment exports
    if (
      # Export each KEY=VALUE exactly as passed, safely quoted
      for kv in "${envs[@]}"; do
        # shellcheck disable=SC2163
        export "$kv"
      done
      # Execute the hook
      eval "$hook"
    ) </dev/null; then

Workaround

Add </dev/null to any hook that may read from stdin:

[hooks]
    postCreate = "your-command </dev/null"
