sfer.nvim v1.2 — Better Sidebar UX and Quickfix Navigation

v1.2 focuses on internal workflow and rendering improvements for SARIF triage.

Technical Changes

• Added module entrypoint support for require("sfer").setup() via root module initialization.
• Refactored SARIF discovery/loading flow:
  • Shared SARIF file lookup path
  • Shared rule-map loading path
  • Added :SarifQuickfix command for direct quickfix population
• Adjusted startup behavior:
  • Auto-open now runs only for directory-based startup flow
  • Manual command path remains available (:SarifSidebar)
• Implemented quickfix export pipeline:
  • Exports full flow steps when available
  • Fallback to base location when no flow exists
  • Scope-aware export from sidebar selection (all / rule / alert)
• Added target-buffer highlighting for quickfix navigation:
  • Highlights current quickfix location in source buffer (not only in quickfix window)
  • Tracks movement through quickfix updates
• Reworked sidebar rendering model:
  • Rule-level fold state
  • Alert-level fold state with collapsed-by-default message blocks
  • Alert entries show file/line and path count; message is toggleable
• Upgraded sidebar UI layer:
  • Structured header with metadata (file, path, rule/alert totals, controls)
  • Divider-based visual sections
  • Theme-linked highlight groups for header, descriptions, messages, and counters
• Improved SARIF parser path resolution:
  • Handles file:// URIs
  • Resolves originalUriBaseIds / uriBaseId
  • Normalizes relative artifact paths against SARIF file directory
• Updated documentation to reflect:
  • New commands/controls
  • New interaction model (l for expand/collapse, c for quickfix export)
