⚡ Bolt: perf: optimize calculateSegmentsScore bounds checking and state maintenance

[AhmmedSamier]

💡 What: Optimized calculateSegmentsScore in language-server/src/core/route-matcher.ts by caching array lengths (pLen and tLen) outside the loop, moving early conditions, and removing intermediate boolean state (isMatch) in favor of immediate early returns (return 0).

🎯 Why: The calculateSegmentsScore loop is a critical hot path used extensively in endpoint suffix matching. In its previous form, length operations like pSegs.length and conditional bounds checking ran multiple times inside the iteration block, contributing overhead along with the maintenance of temporary assignment states.

📊 Impact: The execution time dropped significantly (by ~50-60%) for 5 million loop executions via a local benchmark script (test_perf.ts running against a mock). The overarching scoreMatch function execution time fell from ~1698ms to ~737ms.

🔬 Measurement: Local tests bun run test_perf.ts and bun run test_perf2.ts demonstrated the speed improvement, and standard tests verified functionality: cd language-server && bun test.
