1. Cost-reporter SQL: phpcs:ignore annotations were embedded inside two SQL
string literals (get_daily_spend, get_spend_by_stage), causing MariaDB to
reject both queries and break the Metrics & Costs admin page. Moved annotations
above the prepare() calls. Regression tests added to CostReporterTest.
2. Collector failure observability: catch block in collect_from_all_sources() now
logs structured meta (model slug, HTTP status parsed from exception message,
first 200 chars of error body) so outage incidents are diagnosable post-hoc.
3. run_stages.agent_role back-write: Pipeline_Runner, Article_Worker, and
Content_Generator were calling Run_Stage_State::start() with agent_role=''.
All start() call sites now pass Stage_Display_Map::default_agent_role(stage).
Role written at INSERT only; ON DUPLICATE KEY UPDATE does not include
agent_role — idempotency-key semantics on resume are unchanged.
4. Runware float deprecation: normalize_seed() applied % to a float
(microtime(true) * 1000), triggering PHP 8 deprecation on every image
generation. Fixed with (int) round(...) before the modulo operator.
