fix: code quality improvements across lsp, askcli, appconfig, integrationtests

- lsp/handlers_completion.go: track collectFirstCompletion goroutine in
  inflight WaitGroup (goroutine leak fix)
- lsp/transport.go: use %w instead of %v for error wrapping
- askcli/command_list.go: extract handleListWithFilters shared helper;
  handleList/handleAll/handleReady are now single-liners
- askcli/command_list.go, urgency.go, dep.go: log ParseTaskExport errors
  to stderr instead of returning 1 silently
- appconfig/config_load.go: rename 'any' variable to 'found' to avoid
  shadowing the built-in identifier
- llm/provider.go: add explanatory comment for package-level registry
- integrationtests/ask_test.go: add //go:build integration tag; move
  repoRoot init from init() to TestMain with diagnostic error message
