chore: route rustc through sccache for cold-build wins

Adds .cargo/config.toml setting `rustc-wrapper = "sccache"` so cold
rebuilds (CI, fresh checkouts, post-`cargo clean`) replay previously-
compiled crates from disk instead of recompiling. Warm incremental
builds are unaffected — cargo's own target/ cache dominates there.

Cache lives at `.sccache-cache/` inside the project (gitignored). The
[env] entry uses `force = false` so a developer-set $SCCACHE_DIR in
their shell wins, matching whichever directory the sccache daemon
already adopted.

Requires sccache on PATH. Install: `pacman -S sccache`,
`brew install sccache`, or `cargo install sccache --locked`. Bypass
without editing: `RUSTC_WRAPPER= cargo build`.
