add ClaudeConfig service — layered Claude env + version-keyed slash probe

Builtin-owned, app-wide source of truth for Claude Code's environment
(D-76): skills, custom commands, settings, and permission rules read
from ~/.claude and the repo's .claude, layered local-over-global, watched
for changes. Built-in slash commands come from the stream-json `init`
event, captured by a one-turn probe cached in clide's own dir keyed on
the resolved claude version — so it runs at most once per claude version
per machine. load() stays cheap (version + cache-read + disk + watch);
the paid probe is a lazy ensureProbe() consumers call on first need, so
app-init and tests never pay for a model turn. Wired into the Claude
extension lifecycle and exposed as a builtin singleton.

T-151.
