feat: improve Markdown support and add transcript search functionality

- Add `.cache` to `.gitignore` for temporary build files.
- Introduce Markdown snippets for creating Season 1 and Season 5 show notes in `.vscode/markdown.code-snippets`.
- Update `.vscode/settings.json`:
  - Exclude `node_modules` directory.
  - Adjust quick suggestions to disable them for comments, strings, and others.
- Remove unnecessary `console.log` statements from `episodes.11tydata.js`.
- Add an image file `content/episodes/image.jpg`.
- Implement a transcript search feature:
  - Add `search-transcripts.hbs` to enable searching transcript cues with time markers.
  - Add `transcript-index.11ty.js` to generate a searchable transcript index.
- Update `search-index.11ty.js` to skip processing `<hr>` and `<img>` tags.
- Enhance episode layout with `startAt` query parameter to allow audio playback from a specific time.
- Add a new dependency:
  - `@11ty/eleventy-fetch` for fetching transcripts.
  - `media-captions` for parsing and handling transcript files.
- Update package-lock.json and package.json to include new dependencies.
