chore: allowlist bundled skills to reduce context bloat (#13)

Skill routing descriptions were eating 19,205 tokens (51% of base context)
for 52 bundled skills, most of which Craig never uses (macOS apps, consumer
hardware, food ordering, iMessage, etc.). Adds allowBundled to whitelist
only 13 relevant bundled skills.

Managed/ClawHub skills (x402 enrichment, media-generation, etc.) are
unaffected by allowBundled and remain enabled.

Projected savings: ~12,000 tokens from skill routing alone (~32% of total
base context).
