feat(progress): add per-language progress reporting to scope-resolution phase

[magyargergo]

Summary

Fixes the frozen progress bar during scope resolution on large repos (#1741). The scope-resolution phase can run 74+ minutes on repos with 22K+ Java/Kotlin files, but previously emitted zero progress updates — the CLI bar sat at ~49% with a stale "Parsing code" label, making users think the tool was stuck.

Before: ████████████▒▒▒▒▒▒▒▒▒▒ 49% | Parsing code (2560s) — frozen for 74 minutes

After:

████████████▒▒▒▒▒▒▒▒▒ 54% | Resolving types (Java — extracting (5,000/10,903 files)) (15s)
████████████▒▒▒▒▒▒▒▒▒ 55% | Resolving types (Java — building scope model) (312s)
█████████████▒▒▒▒▒▒▒▒ 56% | Resolving types (Kotlin — resolving references) (89s)
█████████████▒▒▒▒▒▒▒▒ 57% | Resolving types (Kotlin — emitting edges) (45s)

Changes

• Add scopeResolution to the PipelinePhase type union and PHASE_LABELS
• Add onProgress callback to runScopeResolution — reports periodically during the extract loop (~50 updates per language) and at each sub-phase boundary (building scope model → resolving references → emitting edges)
• Wire progress through scopeResolutionPhase with pre-counted file totals, per-language labels, and pipeline-wide percent mapping (90–95 internal → 54–57% display)
• Re-allocate mro/communities/processes percent ranges to 95–100 to maintain monotonic progress after scope resolution
• Add scopeResolution to mro's deps — latent ordering fix since mro reads EXTENDS edges that scope resolution writes via preEmitInheritanceEdges

Test plan

• All 904 scope-resolution unit tests pass
• All 19 pipeline runner tests pass
• All 28 worker pool integration tests pass (17 passed, 11 skipped as expected)
• TypeScript compiles clean (tsc --noEmit)
• Pre-commit hooks pass (lint-staged + typecheck)
• Manual verify on a large Java/Kotlin repo (miracleAi-new or similar) — confirm progress bar updates during scope resolution instead of freezing
