docs: add blog post reflecting on experiences at GIDS 2026

[Ajith-kumar-in]

What did you do?

Summary of changes:

• Added new blog post content/blog/my-week-at-gids.md — GIDS week reflection with TOML front matter (slug, type, authors, description, tags / categories, hero image).
• Added hero image at static/images/2026/my-week-at-gids/header.png (custom GIDS / Team Incubyte collage).
• Removed the temporary placeholder header.jpg under the same folder so the post only references the real asset.
• Aligned post structure with other blog posts (single-line paragraphs, horizontal rules between sections) and ran Prettier per repo .prettierrc (no prose hard-wrap).
• Small copy fixes: “Day 2” for the Scot Davis keynote section; networking line (“that, and most… were happy…”).

Why did you do it?

• New post — Publish a personal write-up of GIDS Bangalore (architecture, AI, accessibility, community, Incubyte / SCI) from the draft you had in gids_experience_blog.md.
• Hero image — Front matter pointed at /images/2026/my-week-at-gids/... but the file was missing, so the header broke; adding header.png fixes the listing and single-page hero.
• Placeholder removal — Avoid shipping a duplicate of another post’s JPEG when the final art is the PNG collage.
• Prettier / style — Match existing blog markdown style and repo formatting; undo accidental --prose-wrap always style if that ever landed locally.
