fix: feed QA guide + issue context to agentic reproduce loop

Root cause: runAgenticLoop never read the QA guide — agent saw
"No issue context provided" for issues. Now reads qaGuideFile,
parses structured fields, and injects into system prompt.

Also: fetch issue body via gh issue view in workflow, increase
budget to 120s/30 turns, add focus reminders, smarter stuck
detection (50px grid normalization + action-type frequency),
reject invalid click targets, add loadDefaultWorkflow and
openSettings convenience actions, strategy hints in prompt.

Fix pre-existing typecheck error in eslint.config.ts.
