fix(observer): hook-resolver — split combined matchers (Edit|Write)

Final-review followup. .claude/settings.json uses regex-style combined
matchers like "Edit|Write"; transcript writes per-tool PreToolUse:Edit.
Split on | when building map so per-tool counts resolve. Also sync
spec doc loadHookMap -> buildHookMap (impl name).
