Spectral decomposition (eigenvalue computation) removed — it was
only used by the spectral-save CLI command. The spectral embedding
reader and query engine features remain (they load pre-computed
embeddings from disk, no faer needed).
Removes: faer, nano-gemm, private-gemm, and ~220 other transitive
dependencies. Significant build time and artifact size reduction.

Use rustls instead of default native-tls (aws-lc-sys) for HTTPS.
Saves ~80 MB of build artifacts. Applied to both main crate and
telegram channel daemon.
Also: tracing default-features = false (Kent's edit).
