Implements cookie consent using vanilla-cookieconsent v3 to comply with
GDPR requirements. Analytics scripts are blocked until user consent is
obtained.
## Changes
**Library Integration**
- Added `vanilla-cookieconsent@3.1.0` to `_config.yml` third-party
libraries with SRI hashes
- Created `_scripts/cookie-consent-setup.js` with consent modal and
settings configuration
- Added CSS/JS includes in `_includes/head.liquid` and
`_includes/scripts.liquid`
**Analytics Blocking**
- Modified analytics scripts in `scripts.liquid` and
`distill_scripts.liquid` to use conditional `type="text/plain"
data-category="analytics"` when consent is disabled
- Blocks Google Analytics, Cronitor, Pirsch, and OpenPanel until consent
granted
- Library automatically converts blocked scripts to executable on user
acceptance
**Configuration**
- Added `enable_cookie_consent` flag (default: `false`)
- Cookie categories: `necessary` (always on), `analytics` (optional)
- 182-day cookie expiration, auto-clear on rejection
## Implementation
```liquid
{% if site.enable_cookie_consent %}
<script type="text/plain" data-category="analytics" async src="...gtag.js"></script>
{% else %}
<script async src="...gtag.js"></script>
{% endif %}
```
Enable in `_config.yml`:
```yaml
enable_cookie_consent: true
```

> <issue_description>Hi,

> since I am from Europe and want my site to be accessed by EU citizens
I need to ask users if they are ok with the use of cookies. Adding a
dialogue by default that that asks the user before any cookies /
localStorage are used would be nice.
>
> I have integrated the dialog from
[https://www.cookieconsent.com/](https://www.cookieconsent.com/) on [my
website](http://hschwane.github.io) and am happy to file a PR if you are
interested. However It is not shown directly at the top, but below the
menu bar for some reason. Not sure how to fix that.

> To answer your question about positioning, the menu bar has the
absolute position at the top of the page and keeps moving with
scrolling. You can change that behavior in `_config.yml` by setting
`navbar_fixed: false` (see [line
27](https://github.com/alshedivat/al-folio/blob/master/_config.yml#L27)).
If you send a PR with basic functionality, I can help with adjusting the

> @hschwane, thanks for providing an implementation based on
`ihavecookies`! I looked through alshedivat/al-folio#223. It seems like
to be able to correctly (un)block different types of cookies (all of
which are third-party cookies) requires adding quite a bit of extra
JavaScript (including adding it directly to posts or pages in some
cases, e.g., when posts embed youtube videos or other external content).
This approach will put some extra burden on contributors and maintainers
of al-folio down the line.
>
> By the way, the dialog from https://www.cookieconsent.com/ is similar
in that sense as it requires to manually add ALL scripts that use
cookies. So, if someone contributes a new feature to al-folio that uses
cookies, the contributor would have to go and update the cookie consent
dialog as well (or edit quite a bit of JS if `ihavecookies` is used).
>
> Thinking about this more, I currently see only three options:
> 1. If we want to have cookie consent as a core part of al-folio (which
can be easily enabled or disabled), it needs to be a service that
automatically identifies and blocks cookies, without putting an extra
burden on the contributors or maintainers. The hosted version of [Cookie
Consent by Osano](https://www.osano.com/features/consent-management) is
an example.
> 2. Another option is to provide a very minimalistic cookie consent
dialog which simply says that the website uses cookies, without an
option to opt-in or opt-out (e.g., see the open-source edition of
[Osano](https://www.osano.com/cookieconsent/download/)).
> 3. Finally, not have cookie consent as part of al-folio, and make the
user responsible for figuring out whether they need a consent dialog and
which service to use.

This pull request significantly expands and clarifies the documentation
for the al-folio Jekyll theme, focusing on improved file structure
explanations, enhanced quick reference guides, and the addition of a
comprehensive analytics setup guide. The changes make it easier for
users and contributors to understand the project organization, available
features, and configuration options, especially regarding CV formats,
teaching pages, and analytics integration.
**Key documentation and structure improvements:**
*Expanded file and collection structure:*
- The file structure documentation in
`.github/agents/customize.agent.md` and `.github/agents/docs.agent.md`
now details all major directories, including new and existing
collections such as `_books/`, `_teachings/`, `_scripts/`, `_plugins/`,
and expanded `assets/` subdirectories. It also covers new configuration
and utility files, making it easier for users to locate and understand
the purpose of each file or folder.

*Documentation and quick reference enhancements:*
- The quick reference table in `.github/agents/customize.agent.md` has
been updated to include new actions like adding teaching pages, setting
up analytics, improving SEO, and ensuring accessibility, with more
precise documentation links.
- The documentation map now lists all major guides (e.g.,
`QUICKSTART.md`, `INSTALL.md`, `TROUBLESHOOTING.md`, `ACCESSIBILITY.md`,
`ANALYTICS.md`, `SEO.md`), providing a clearer overview of available
resources.

**Feature and configuration documentation updates:**
*CV/resume format guidance:*
- The CV documentation now clarifies that users can maintain both
RenderCV and JSONResume formats simultaneously, with clear instructions
on switching between them and deleting unused files if desired.

*Teaching pages and new collections:*
- Adds documentation for the new `_teachings/` collection, including
required frontmatter and support for course materials, as well as
updates to enable/disable teaching and books pages via `_config.yml`.

*Analytics integration:*
- Introduces a new `ANALYTICS.md` guide with detailed setup instructions
for Google Analytics, privacy-friendly alternatives (Plausible, Pirsch,
Openpanel, GoAccess), GDPR considerations, and a comparison table to
help users choose the right analytics provider.
- The configuration documentation now references analytics setup and
related configuration options.

These updates collectively make the documentation more comprehensive,
actionable, and user-friendly for both new and advanced users.

Refactored the script in _scripts/search.liquid.js to use a more
efficient Liquid 'where' filter to find the home page title. This
replaces an inefficient for loop that iterated through all site pages.

Fixes issue #3243
Add CV PDF link to social icons
- Added CV icon to social media links section
- CV appears after LinkedIn icon in the contact section
- Uses academicons CV symbol for consistent academic styling
- Links to `/assets/pdf/CV_Schirren.pdf` and opens in new tab
- Updated `_includes/social.liquid` to handle `cv_pdf` field
- Updated `_data/socials.yml` with CV configuration
- Updated `_scripts/search.liquid.js` with cv search functionality
Currently, the `site.giscus.theme` option is ignored because
`giscus.liquid` always computes the theme as light/dark based on the
current site theme. This PR allows users to configure separate light and
dark giscus themes in `_config.yml`, which will support dynamic updates
when switching between light, dark, or system themes.
Fixes#3269
Earlier there was a tag in the `_config.yml` file to exclude the posts
from the search results. I could no longer find that option and hence
modified the `search.liquid.js` file.
It basically checks if the `posts_in_search` tag is true or not.
