v0.2.2

Corrects the request path for every v2 endpoint across the market, message,
client_preference, order, preference, watchlist, session, price_alert, and
user_account resource groups.

The frozen catalog composed each path as /{target}{uri_template}, doubling the resource segment
the v2 template already carries (for example /market/v2/market/...), so every one returned 404.
The generator now emits the documented /v2/... template, served under the existing /TradingAPI
base. Four order/preference routes whose upstream uri_template is itself wrong get verified
overrides. Every corrected route was checked against the live CIAPI demo.

Fixes #15, #16, #17, #18, #19, #20, #21 (via #22).

See the changelog for details.
