* fix(#1013): resolve worktree.baseRef from user/global settings cascade
cmdWorktreeBaseCheck resolved worktree.baseRef from the project checkout's
.claude/ only (settings.local.json then settings.json). A user/global
worktree.baseRef:"head" — the layer /config writes and the harness honors,
and the only sensible place for a machine-wide preference — was invisible. On a
phase lane (HEAD ahead of origin/HEAD, or no origin/HEAD symref) base-check
returned shouldDegrade:true and execute-phase forced sequential execution,
silently losing the parallel worktree execution the user configured.
CLAUDE_CONFIG_DIR (relocated user config dir) was also ignored.
resolveEffectiveBaseRef now accepts an optional user/global config dir and reads
its settings.json as a third, lowest-precedence layer (project local > project
shared > user/global). cmdWorktreeBaseCheck resolves it via
getGlobalConfigDir('claude'), which honors CLAUDE_CONFIG_DIR. The existing
project-level reads stay as higher-precedence overrides and the injectable
readFile seam is preserved, keeping the unit tests hermetic.
