feat(brain): setup runs gbrain detection + conditional SKILL.md regen 

At the end of install, ./setup now:
  1. Runs bin/gstack-gbrain-detect, persists the result to
     ~/.gstack/gbrain-detection.json
  2. If gbrain_local_status == "ok", regenerates Claude-host SKILL.md
     via `bun run gen:skill-docs:user --host claude` so the user's
     local install picks up the compressed brain-aware blocks
  3. If gbrain isn't detected, leaves the canonical no-gbrain SKILL.md
     files in place (zero token overhead) and surfaces the
     gstack-config gbrain-refresh path for users who install gbrain
     later

Together with the prior two commits, this completes the setup-time
conditional un-suppression: brain-aware blocks render iff the user
has gbrain installed, regardless of which CLI host they're on.

# ─── GBrain detection + conditional SKILL.md regen ──────────────────────
#
# Detect whether gbrain is installed and persist the result to
# ~/.gstack/gbrain-detection.json so gen-skill-docs can decide whether to
# render GBRAIN_CONTEXT_LOAD and GBRAIN_SAVE_RESULTS blocks. If detected,
# regenerate the Claude-host SKILL.md files with the un-suppressed
# (compressed) brain-aware blocks via `bun run gen:skill-docs:user`.
#
# If gbrain is not detected, the canonical no-gbrain SKILL.md files
# (which were just generated above by `gen:skill-docs --host claude` if
# applicable, or which are checked in) stay as-is. Zero token overhead
# for non-gbrain users.
#
# Users who install gbrain after running ./setup should re-run setup OR
# call `gstack-config gbrain-refresh` + `bun run gen:skill-docs:user`.
