Adds the parser and the probe behind the source control panel: one `git status --porcelain=v2 --branch --show-stash -uall -z` per refresh, read through `Host::git` so the NUL stream survives a remote workspace byte for byte (`git_lines` would reassemble it into one giant line). - `parse_porcelain_v2` is pure and infallible: headers, `1`, `2`, `u`, `?` and `!` records, submodule sub-state, rename scores. A `2` record spends two NUL tokens, so the parser parks the half-built entry and takes the *next* record as the old path — a regression test asserts the row behind a rename is not swallowed. - `probe_status` costs three round trips: `rev-parse`, `status`, and one `read_dir` of the git dir for the sequencer operation. The operation precedence mirrors git's own `wt_status_print_state`; only a parked rebase pays for a second `read_dir` to tell `am` from rebase and `-i` from plain. - `StatusIndex::build` folds a status into the file tree's lookup, and drops the per-file map past `MAX_DECORATED_FILES`. Two behaviours were measured on git 2.50.1 and shaped the code: - `status.aheadBehind=false` does *not* suppress `# branch.ab` for porcelain v2 (the config is documented for non-porcelain formats), and `--no-ahead-behind` prints `+? -?` rather than dropping the line. So `+? -?` parses as *unknown*, never as in sync, and the `rev-list --left-right --count` fallback fires only when the line is missing — unconditionally re-asking would cost a remote RPC on every refresh for a number we almost always already have. - `-c core.quotePath=false` is a no-op under `-z`, which disables C-quoting on its own. It is kept for consistency with the other git invocations, not because it fixes anything here. `repo_home` becomes `pub(crate)` so the probe can reuse the one `rev-parse` that already resolves root, git dir and common dir.
