fix: add bare function fallback to CALL_PREFIXES, fix IMPORT_PATTERNS order, update pipeline diagram

- CALL_PREFIXES: add bare "function" as last fallback — Kotlin uses
  @function for both calls and definitions (no function.call capture)
- _find_arglist_node: remove template_string from arglist detection
- IMPORT_PATTERNS: require_relative before require (Ruby fix)
- pipeline-overview.txt: remove .gitignore, add min_coverage=0.8 + core/outlier
- DEFAULT_COVERAGE=0.8, frequency_filter at fixed 0.2
