docs: T3 Code benchmark against bun check and tsc 7

[t3dotgg]

The README had no numbers for a real Effect project, and no comparison with the new bun check in Bun.

This adds a "Benchmark: T3 Code" section below the slop line. It has two tables, without and with the Effect diagnostics, with the time, the multiplier against tsc 7 and a text bar for each checker. The numbers are the totals from the T3 Code run (five projects, Apple M5 Max). The section links pingdotgg/t3code#16704 for the per-project table.

Made by Claude Opus 5.5 in Claude Code, running in T3 Code.
