feat: add opt-in reference data cache shared between instances

Add a file-based, inter-process cache for the reference data fetched once
at startup so multiple ticker instances on the same machine can share it,
speeding up startup and reducing provider request throttling (#369).

Enabled with --cache or `cache: true`. A single JSON file at
${XDG_CACHE_HOME}/ticker/reference-cache.json (0600) caches the symbol
source map, Yahoo session (cookies + crumb), per-symbol currency, currency
conversion rates, and Coinbase futures underlying mappings, each reused for
up to one hour. Live price quotes are never cached. A stale Yahoo session
is detected and re-established automatically.
