test(cli): synthetic per-test M1 archive — no-window generalize tests go hostless

The two generalize E2E tests whose property is no-window span
resolution (shared-window fallback, intersection semantics) no longer
stream the 6.6 GB host archive: fresh_project_with_data() generates a
deterministic two-symbol M1 archive (SYMA 2024-01..08, SYMB 2024-03..06
strictly inside it, so the intersection differs from symbols[0]'s
window on both bounds) in the exact zip/48-byte-record format
data-server reads, plus geometry sidecars, under the per-test project's
paths.data. Both tests drop their local_data_present gates — they now
run on any host, data mount or not.

~35s and ~50s become 0.74s and 1.14s; the full cli_run binary lands at
~25s (211s at the branch base). Full workspace suite: 247s -> 45.7s.
