Kill reqwest — minimal HTTP client on raw hyper + tokio-rustls

Browse source 
New src/agent/api/http.rs: ~240 lines, supports GET/POST, JSON/form
bodies, SSE streaming via chunk(), TLS via rustls. No tracing dep.

Removes reqwest from the main crate and telegram channel crate.
Cargo.lock drops ~900 lines of transitive dependencies.

tracing now only pulled in by tui-markdown.
