docs: add SwapDK bridge community module
Created by: Vali0x
Adds the SwapDK bridge suite (@swapdk/wdk-protocol-bridge-swapdk-{btc,cosmos,evm,solana,tron}) to the community-modules catalog.
Five new rows in content/docs/sdk/community-modules/index.mdx — one per source-chain package. All rows follow the existing pattern (npm + GitHub links, Type = "Bridge Module", link to per-module docs, author).
New content/docs/sdk/community-modules/wdk-protocol-bridge-swapdk/index.mdx landing page — 155 lines describing the whole suite:
- Community disclaimer callout, matching the wording used for the other third-party modules already in this section.
- When-to-use table mapping five source-chain use cases to the corresponding package.
- Package suite table with peer-wallet mapping and per-package GitHub links.
- Server-side routing explanation (SwapDK swap-engine selects between THORChain, MAYAChain, and Chainflip; downstream code sees a uniform interface).
- Requirements + install snippets for the three most common source-chain variants (EVM, BTC, TRON).
- Two minimal setup examples (EVM->BTC native, BTC->EVM USDC).
- Reference cards linking to the monorepo, the @swapdk npm org, and the community-modules index.
All links point to public github.com/Swap-DK repositories and npm; no non-public references.
