test: add unit tests for URL/path canonicalization utilities

[tanmayjoddar]

Why

Canonicalization is used to merge schemas across variable IDs (e.g., /users/123 and /users/456). Current behavior is untested.

Where

• src/utils/canonicalize.js
• Add: tests/utils/canonicalize.test.js

Acceptance Criteria

• canonicalizePathname() replaces numeric segments with :id
• UUID segments become :uuid
• High-entropy segments become :id
• Root path stays /
• normalizeUrl() removes query/hash and canonicalizes pathname
• npm test passes

Hi @tanmayjoddar, I would like to work on this under GSSoC'26.\n\nI will add focused Jest coverage for src/utils/canonicalize.js: numeric segments, UUID segments, high-entropy segments, root path preservation, and normalizeUrl() removing query/hash while canonicalizing the pathname. I will run the full test suite before opening the PR.
