Builds on @Shizoqua's verified provider core (#201) and resolves the three
open-box blockers from review:
- No built-in feed catalogue: the shipped DEFAULT_FEEDS routes (/stock/notice,
/stock/news) don't exist in RSSHub, so a default run scored every bar 0.0.
Feeds are now declared explicitly in config (event_feeds = list of
{name, route_template, event_type, code_style}); DEFAULT_FEEDS is empty, so
there is nothing to silently rot as RSSHub routes evolve.
- Per-symbol code formatting: a feed declares a code_style
(raw / bare / exchange_prefix), so dotted backtest codes (600519.SH) are
rewritten to the form a route needs (e.g. SH600519 for xueqiu-style routes).
- No silent all-zero scores: each fetch failure is logged per feed/code, and
query_events raises EventProviderError when every fetch failed (configured
but fully unreachable) instead of returning an all-zero event_score that
reads as "sentiment considered, no signal". A reachable feed that returned
no items stays a legitimate empty result.
PIT discipline, defusedxml hardening, the pluggable scorer, and the
engine/runner wiring are otherwise unchanged. Adds 12 tests for the code
styles, config parsing/validation, and the loud-failure path.
Thanks @Shizoqua (#201) for the provider core.
