The aarch64-unknown-linux-gnu release build for `deepseek-tui` failed in
release.yml run 25327475634 with:
openssl-sys v0.9.111: 'openssl/opensslconf.h' file not found
`crates/tui/src/main.rs` was the only crate in the workspace pulling
`reqwest` with `default-features = false, features = ["native-tls", ...]`
— every other crate (including the dispatcher in `crates/cli`) already
inherits the workspace default `["json", "rustls"]`. The aarch64 leg
builds with `cargo zigbuild --target aarch64-unknown-linux-gnu.2.28`,
whose zig sysroot does not ship openssl headers; the matching native-tls
job for v0.8.9 succeeded by chance against an earlier runner image but
the current `ubuntu-24.04-arm` image no longer satisfies openssl-sys's
header probe under zigbuild.
Switching the TUI's reqwest features from `native-tls` to `rustls` brings
it in line with the rest of the workspace and removes nine crates from
the build graph entirely (`openssl`, `openssl-sys`, `openssl-probe`,
`openssl-macros`, `native-tls`, `hyper-tls`, `tokio-native-tls`,
`foreign-types`, `foreign-types-shared`). reqwest 0.13.1 already uses
`rustls-platform-verifier` for OS trust-store integration, so end-user
TLS behavior against api.deepseek.com remains equivalent.
Verified locally:
- cargo clippy --workspace --all-targets --all-features --locked passes
- cargo build --release -p deepseek-tui --locked succeeds
- cargo fmt --all -- --check is clean
- no source code in `crates/` references native-tls / openssl directly
This is a release-pipeline-only fix; no user-visible feature changes.
