Route scanner picks up .test.ts files inside routes directory

Problem

Test files co-located in the routes/ directory can be picked up by the route scanner. While .test.tsx files are now filtered (fixed in #95), the pattern relies on the .tsx extension check as a secondary guard for .test.ts files.

Current state

• scanRoutes and generateRouteMap now filter .test.* files
• Only .tsx files are processed, so .test.ts files are excluded by extension check
• The filtering is consistent but relies on two independent checks

Suggestion

Low priority — current behavior is correct. The test pattern filter acts as defense-in-depth.

Closing as wontfix. The route scanner already correctly excludes .test.ts files via two independent guards:

1. TEST_PATTERN = /\.test\.[^.]+$/ explicitly filters test files
2. Extension check only accepts .tsx/.ts route files

Current behavior is correct — this is defense-in-depth working as designed. The issue body confirms "current behavior is correct" and "low priority." No code change needed.
