[Change Request] - Write a computeTriageScore function

Description

Context
Change requests should be rankable by importance, so the important ones get reviewed first instead of getting stuck behind trivial ones. We want a single, self-contained function that takes a few numbers about a CR and returns a score. It has no database access, just math, so it's easy to test. Something else will call it and store the result.

Task
Write and test a function computeTriageScore(input): number.

Acceptance Criteria

• Lives in its own file (e.g., utils/triage-score.utils.ts), exported, no DB calls.
• Takes a typed input object with: CR type; proposed budget magnitude (budget CRs only); blocking count (how many WPs this WP blocks); days until start; days until end; timeline-change amount + direction (a change that pushes the date later scores higher than one that pulls it earlier).
• All weights are named constants at the top of the file with comments, so they're easy to tune later.
• Higher = more urgent. A more overdue deadline scores higher than one further out.

Start by checking the existing utility and test conventions, then use the proposed utils/triage-score.utils.ts location as the entry point. Define the typed input and named, commented weights from the acceptance criteria, and add tests for CR types, budget and blocking counts, deadlines, and timeline direction. Done means the exported function is self-contained, has no database calls, and its tests verify that higher urgency produces higher scores.
