Bun.serve: rename `h3`/`h1` options to `http3`/`http1` (oven-sh#30583)

## What

Renames the `Bun.serve()` `ServerConfig` HTTP/3 options from the
abbreviated `h3` / `h1` to the spelled-out `http3` / `http1`.

```ts
// before
Bun.serve({ tls, h3: true, h1: false, fetch })

// after
Bun.serve({ tls, http3: true, http1: false, fetch })
```

These options have not shipped in a release yet, so this is a clean
rename with no backwards-compat aliases.

## Changes

- **`src/runtime/server/ServerConfig.zig` / `server.zig`**: rename the
`ServerConfig` struct fields and the JS option lookups (`arg.get(global,
"http3")`, etc.); update the validation error messages and the
unix-socket warning.
- **`packages/bun-types/serve.d.ts`**: rename the type declarations,
drop the incorrect "(and HTTP/2)" from the `http1` JSDoc (Bun.serve does
not support HTTP/2), and mark both options `@experimental`.
- **`docs/runtime/http/server.mdx`**: add an "HTTP/3 (QUIC)" section
documenting `http3` / `http1`, Alt-Svc, the unix-socket limitation, and
the experimental status.
- **Tests**: update `Bun.serve({ http3, http1 })` call sites, test
names, and the validation error-message assertion across the HTTP/3
suites (`serve-http3.test.ts`, `serve-protocols.test.ts`,
`body-stream.test.ts`, `fetch-http3-client.test.ts`,
`fetch-http3-adversarial.test.ts`, `direct-readable-stream.test.tsx`,
`fetch-h3.ts`, `packages/h3blast/`).

## Notes

- The internal `uws.AnyRequest` union variants (`.h1`/`.h3`) are left
as-is — those tag a transport, not a config option.
- The `fetch()` `protocol` option (`"http1.1" | "h1" | "http2" | "h2" |
"http3" | "h3"`) is unchanged; it already accepts both spellings.
- `zig:check` and the `bun-types` `tsc` test pass locally. The full
HTTP/3 test suite will run in CI.

deflake hot.test.ts: fix duplicate error handling and buffer manageme…

…nt (oven-sh#28202)

The three sourcemap tests (generation, loading, loading with large
files) used a `continue outer` pattern in their error-handling loops.
When a duplicate/stale error was encountered, `continue outer` jumped
back to reading the next stderr chunk, but any remaining lines from
`str.split("\n")` that had not yet been processed were discarded because
`str` was set to `""` inside the inner loop. This lost data and could
cause the test to hang waiting for output that was already consumed and
thrown away.

Additionally, the bundler processes in the sourcemap loading tests used
`stdout: "inherit"` / `stderr: "inherit"`, which could cause pipe buffer
backpressure blocking the bundler.

Fixes both issues with a shared `driveErrorReloadCycle` helper that:
- Preserves unprocessed lines when encountering duplicate errors (uses
`lines.pop()` for trailing partial lines and re-buffers remaining lines
via `lines.slice(i + 1)`)
- Pipes bundler stdout/stderr to `ignore` to avoid pipe buffer
backpressure
- Races `bundler.exited` against the reload driver for early-exit
detection in the two bundler-based tests

Verification: Format and Lint JavaScript CI checks pass. Buildkite build
#39875 still compiling at time of review. Only
`test/cli/hot/hot.test.ts` changed (test-only deflake, no production
code). Jarred's CHANGES_REQUESTED about the nonce mechanism was
addressed in commit 50f3f4e (nonce removed). No TODO/FIXME/HACK in
added lines. The driveErrorReloadCycle helper correctly preserves
partial line fragments and remaining unprocessed lines, prevents double
onReload calls via the triggered flag, and uses Buffer.alloc per
test/CLAUDE.md convention.
