feat(chain): classify outpoints by chain-level spend eligibility
Adds classify_outpoints, which decides per-output whether it's settled,
immature, or pending (trusted, untrusted, or unknown) based on its unsettled
ancestry. Trust is resolved with a memoized ancestry walk: a tainting ancestor
makes it untrusted, one missing from the view makes it unknown, and ancestors
shared by several outputs are only walked once.
