Add Tooling navbar dropdown linking to Gaffer

[George-Payne]

Adds a new Tooling dropdown to the docs navbar, between Clients & APIs and Developer Resources, with a single entry linking out to the Gaffer mini-site:

… · Clients & APIs · Tooling ▾ · Developer Resources
                      └─ Gaffer (Projections tooling) → https://gaffer.kurrent.io

The external link gets the theme's external-icon + new-tab behaviour automatically, matching the other outbound nav entries. The dropdown is intentionally a container for more currently-undocumented tools to be added later.

1. Non-canonical Gaffer URL 🐞 Bug ⚙ Maintainability

Description

The new navbar link uses https://gaffer.kurrent.io (no trailing slash) while existing docs
consistently reference https://gaffer.kurrent.io/, creating inconsistent references and
potentially an extra redirect if the target site normalizes trailing slashes.

Code

docs/.vuepress/configs/navbar.ts[37]

+            {text: "Gaffer (Projections tooling)", link: "https://gaffer.kurrent.io"},

Evidence

The navbar adds Gaffer without a trailing slash, while an existing docs page links to the same site
using the trailing-slash form multiple times, showing an inconsistency introduced by this PR.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The navbar entry for Gaffer uses a non-canonical root URL (missing trailing slash) compared to other documentation references.

## Issue Context
Other docs pages already link to the Gaffer site using the trailing-slash form (`https://gaffer.kurrent.io/`). Keeping the navbar consistent reduces future churn (search/replace, audits) and avoids possible extra redirects.
