reqwest_client: Drop stale connections with keepalives (#59929)
## Summary

Tune the shared `ReqwestClient` builder so HTTP connections that have
silently gone bad on a flaky network path are detected and dropped
rather than reused.

A stale, reused HTTP/2 connection (after a NAT/conntrack timeout, a
silent reset, or a degraded path) is a common source of intermittent
TLS `BadRecordMac` errors against long-lived endpoints such as
`cloud.zed.dev`. The client already retries these (`HttpSend` is
retryable with exponential backoff), but users still see periodic
multi-second stalls and "connection error" warnings.

These settings make the client probe and recycle connections instead of
sending a request's first records into a connection that is already
dead:

- `tcp_keepalive(30s)` — surface dead TCP connections instead of reusing
them.
- `pool_idle_timeout(30s)` — bound how long an idle connection lingers
in the pool.
- `http2_keep_alive_interval(15s)` / `http2_keep_alive_timeout(10s)` /
`http2_keep_alive_while_idle(true)` — ping idle HTTP/2 connections so
broken ones are torn down.

All three constructors (`new`, `user_agent`, `proxy_and_user_agent`) go
through `builder()`, so every Zed HTTP client picks this up.

## Notes

- Values are conservative; they can be tightened if stale-connection
  errors persist.
- `tcp_keepalive_interval` is not yet available in the pinned
`zed-reqwest`
  fork rev, so only the initial keepalive idle time is set here.

## Verification

Behavior is network-dependent, so there is no deterministic test.
Verified
that the crate builds (`cargo check -p reqwest_client`). The change is
being validated empirically against a setup that reproduces the
`BadRecordMac` errors.

Release Notes:

- Improved resilience to intermittent network errors by detecting and
dropping stale HTTP connections instead of reusing them.

Licensing

Zed source code is licensed primarily under GPL-3.0-or-later, with Apache-2.0 components where marked.

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
