Add 5 posts (EN + ZH): fully on-chain SVG NFTs, the CRLF art trap, a Chainlink VRF v2.5 lottery, page-by-page PDF verification, JPA @Version

Five posts with custom OG + banner and hire CTAs. Three are web3, giving that category its first posts — /categories/web3/ previously 404'd while the index advertised it as '0 posts - coming soon'. Backdated where the work genuinely is older: the foundry-nft and hardhat-smartcontract-lottery commits date to 2024-08-15..19, so those two posts fill the empty 2024-10 and 2024-12 archive months with updatedDate holding the real date. The two 2026-08-19 posts use their real work date. TERMINALS/BANNERS entries for all five slugs are committed this time (both generators were clean; diffs verified purely additive).
