Description

Adds Basics of Mechanical Engineering (BME) as a new subject under Semester 1.

Files Added:

• app/sem1/bme/constants.ts — chapter list and types (ch0–ch7)
• app/sem1/bme/layout.tsx — subject layout with Navbar + Sidebar
• app/sem1/bme/components/sidebar.tsx — responsive chapter navigation
• app/sem1/bme/[chapter]/page.tsx — dynamic chapter page with prev/next navigation
• app/sem1/bme/content/chapter0.tsx — Course Outline content

Files Modified:

• app/components/subjects.tsx — added BME to Semester-1 list and available array

Note: Only ch0 (Course Outline) has content. Ch1–Ch7 show "Coming Soon" and will be added in a follow-up PR. Follows the same structure as the approved CLE subject PR #112.

How Has This Been Tested?

Tested locally using npm run dev. Verified BME appears as a clickable subject under Semester-1 on the homepage, sidebar renders correctly on desktop and mobile, ch0 loads with full content, and ch1–ch7 show "Coming Soon" as expected.
