`build.rs` only declared `rerun-if-env-changed` for `DEEPSEEK_BUILD_SHA`
and `GITHUB_SHA`. With no `rerun-if-changed` directives, Cargo cached
the build-script output across commits and the embedded short-SHA in
`DEEPSEEK_BUILD_VERSION` (visible in `--version`) went stale until the
next `cargo clean`.
Add a `cargo:rerun-if-changed=<workspace>/.git/HEAD` directive in both
the `cli` and `tui` build scripts. Handle both layouts: a regular
checkout (`.git` is a directory) and a worktree (`.git` is a pointer
file containing `gitdir: <path>`), so the SHA stays current in either
case.
Verified: touching `.git/HEAD` now triggers a recompile of the affected
crate; `--version` reflects the current commit on the next build.
