Research CLI: alias --status complete to the stored done value (#2515)

`odysseus-research list --status complete` returns an empty result on
any real corpus. The CLI accepts `complete` as a `--status` choice (the
user-facing label), but the writer in
`services/research/research_handler.py` stores `status="done"` when a
run finishes (and the legacy `src/research_handler.py` copy does the
same). The list filter at `scripts/odysseus-research` was a literal
string compare:

    if args.status and (data.get("status") or "") != args.status:
        continue

so `--status complete` filtered every finished record out, and the user
saw nothing — even though `odysseus-research list` (no filter) listed
them fine and `show RP_ID` worked on the same files. The other
documented choices — `running`, `cancelled`, `error` — are stored
verbatim by the writer, so the surface mismatch is just on `complete`.

Add a small `_STATUS_CLI_TO_STORED = {"complete": "done"}` map and run
`data.get("status")` through `_status_matches(...)` before comparing.
The other CLI choices fall through unchanged, so the filter still
matches them verbatim. A `None` or non-string `status` (corrupt JSON)
is coerced to `""` and never matches `complete`, so a half-written
record can't sneak past the filter.

`tests/test_research_cli_status_filter.py` covers all four documented
choices, the non-string / missing status case, and pins that the
verbatim choices are NOT rewritten — a blanket mapping that turned
every CLI choice into a stored variant would just re-introduce the
empty-result bug on the running/cancelled/error paths.

Part of #2122.

+"""`odysseus-research list --status complete` was returning nothing.
+
+The CLI's `--status` argparse choice is "complete" — that is the user-facing
+label — but the writer in `services/research/research_handler.py` stores
+`status="done"` for a finished run (and the older `src/research_handler.py`
+copy does the same). The list filter was a literal string compare, so
+`--status complete` matched zero records on any real on-disk corpus.
+
+These tests pin the alias so the friendlier CLI word keeps matching the
+stored value. The other choices (`running`, `cancelled`, `error`) are
+stored verbatim, so they must NOT be rewritten by the alias map.
