build_table returns (table, reverts_column, wikitext_parser) but the
jsonl test helper still unpacked two values, so test_jsonl_noargs and
test_jsonl_tsv_equivalence failed with a ValueError before reading any
output. Also update the docstring, which still described the two-value
return.

Nate has given up on getting wikiq to output parquet directly because it
makes too many unpredictable large memory allocations. The workflow now
outputs JSONL in a single pass and then uses spark (wikiq_spark) to index
it as parquet in a second pass.
Remove the parquet output path along with the machinery that existed only
to support it: checkpoint files, resume temp-file merging, namespace
partitioning, and file rotation (--partition-namespaces,
--max-revisions-per-file). Resume support remains for JSONL output, where
the resume point is derived from the last complete line of the output
file. Also remove the parquet tests and baseline files.

RegexPair.matchmake crashed with a TypeError when a capture-group
pattern was applied to a revision whose text or comment was deleted or
suppressed (content is None). Guard both matching paths against None,
and make the no-capture-group path emit a None column for such
revisions instead of omitting the key entirely.
This carries forward the fix Kaylea Champion and Mako Hill made on the
mako_changes-20230429 branch (7e6cd5b), which predated the rewrite.
Adds a unit test for matchmake(None) and an end-to-end test against the
ikwiki dump, which contains revisions with deleted text and comments.

Per-page adaptive parse skip: once mwparserfromhell times out on a
revision of size N bytes, force-timeout future revisions on the same
page whose text is >= N bytes instead of waiting another 60s on each
one. State resets per page, so well-behaved pages are unaffected.
Motivated by zhwiki bot-vandalism log pages (e.g. ns=4
'Wikipedia:当前的破坏/...' at 4.6GB across 6133 revisions) where every
revision triggers the 60s SIGALRM, blocking the worker for hours.
- Implement per-namespace resume points (dict mapping namespace -> (pageid, revid))
to correctly handle interleaved dump ordering in partitioned output
- Extract resume functionality to dedicated resume.py module
- Add graceful shutdown handling via shutdown_requested flag (CLI-level only)
- Use lazy ParquetWriter creation to avoid empty files on early exit
- Refactor writing logic to _write_batch() helper method
- Simplify control flow by replacing continue statements with should_write flag
