Configurable schema cache location and TTL (#505)

* feat: add cache settings helpers (parseTtl, resolveCacheDir)

* feat: add getCacheSettings and cache settings type

* feat: use configurable cache location and TTL for schemastore cache

Wires src/utils/schema.ts to the getCacheSettings() helper from Task 2
instead of the hardcoded module-relative .cached_schemastore path and
1-day TTL constant. The require() same-process fast-path (which never
shipped cached schemas with the package) is replaced by an in-memory
Map keyed by resolved cache file path, preserving the RELOADING
background-refetch behavior.

* docs: document cache settings and add changeset

* fix: accept bare-number ttl strings so "0" means always-refetch

* docs: document cache settings in README

Port the schemastore cache settings (cache.path and cache.ttl) into the
README's Advanced Usage section so it stays in sync with the user guide.
tools/update-readme.ts uses the README as the source of truth for the
ADVANCED_USAGE_GUIDE block, so the guide's cache docs would otherwise be
overwritten on the next `npm run update`.

* fix: keep default schemastore cache location unchanged

Per PR review, revert the default cache directory back to its historical
module-relative location (../.cached_schemastore). The changeset now only
adds the cache.path / cache.ttl configuration options; the default location
is unchanged. Users can set cache.path to persist the cache across runs.
