jared 72b2cc3a26 fix: local corpus paths were unreadable on Windows (backslashes eaten)
R-CMD-check / check (push) Successful in 3m35s
R-CMD-check / check (pull_request) Successful in 3m49s
gsub() in regex mode treats backslashes in the REPLACEMENT string as
escape sequences and silently drops them. A Windows corpus path is full of
them, so C:\Users\RUNNER\AppData\... was substituted into the view SQL
as C:UsersRUNNERAppData... and every DuckDB read failed with 'No files
found that match the pattern'.

Effect: uscogdata could not read a LOCAL corpus on Windows at all -- the
bundled fixture included, so the entire test suite failed there, and any
cog_mirror() copy was unusable. Remote https URLs were unaffected, having
no backslashes, which is part of why it stayed hidden.

The bug predates the {long_files} token; it lived in the original {url}
substitution since that code was written. Nothing ever ran on Windows
until the GitHub mirror's check matrix existed, which found it on its
first run: 14 of 15 Windows failures were this, the 15th a downstream
consequence of view registration failing.

fixed = TRUE treats pattern and replacement as literal text. The
regression test reproduces on any platform -- it is string handling, not
filesystem behaviour, so it needs no Windows runner.

jared 99e1e86e37 fix: enumerate long partitions from the manifest instead of globbing
DuckDB cannot expand a glob over generic HTTP -- there is no directory
listing, and allow_asterisks_in_http_paths only forwards the literal
'**/*' as a filename, which 404s. So every remote corpus read failed.
Only local paths worked, which is how the API (a host mount) and the test
fixture run, so nothing ever caught it.

Measured against the published corpus: the explicit list returns the same
46,148,034 rows the hf:// glob does, with hive_partitioning still
recovering year from the paths. Building it from the manifest keeps the
reader host-agnostic rather than binding it to one vendor's protocol.

Also extracts .render_view_sql(). Four test sites had hand-rolled the
{url} substitution -- one commented as doing it 'exactly as
.register_views() does' -- and all four broke on the second token. They
now share the one function that knows the vocabulary, and a new test
renders every SQL file to prove no token survives.
