dgtlmoonandClaude Opus 5.5 ce777a6d60 PDF - Keep the original PDF of the newest two versions (#4549)
* PDF - Keep the original PDF of the newest two versions

The history snapshot of a PDF watch is only the pdftohtml text, and the "last fetched" .html.br
for a PDF is just a checksum, so the actual documents were never kept. Store {timestamp}.pdf
alongside the snapshot (same as {timestamp}.html.br does for HTML) and prune to the newest two
history entries, so the latest two versions are always available for a visual PDF compare.

* Test - Browser PDF test, fix race with an immediate fallback recheck, check the original PDFs are kept

A duplicate queue entry (scheduler + import) can run the html_requests fallback check right
after the failed browser check, so by the time the test looks the error may already be cleared.
Accept both outcomes, the error message itself is covered in tests/test_pdf.py.

Also check both original PDF versions are stored, whichever fetcher got them.

dgtlmoonandClaude Opus 5.5 44fd71679e Puppeteer fetcher - PDF improvements, Handle PDF fetching by Puppeteer directly, cleanup supports (#4547)
* Fetchers - Define raw_content on the base fetcher, give a clear error when a fetcher can't supply the PDF

Fetchers that never set raw_content (puppeteer, playwright, selenium) crashed with
"'fetcher' object has no attribute 'raw_content'" when the response turned out to be a PDF.
Browsers render PDFs in their built-in viewer, so all they have is the viewer HTML; now the
processor reports that plainly instead of crashing or feeding HTML to pdftohtml.

* Puppeteer - Capture the real PDF body when the page turns out to be a PDF

Chrome hands a PDF straight to its built-in viewer, after which page.content and
Network.getResponseBody only return the viewer's HTML. Pause main-frame document responses
with the CDP Fetch domain and, when the Content-Type is application/pdf, copy the body out
before it is continued - a single download, and nothing needs to be known in advance.

content/raw_content then match the requests fetcher's binary handling (md5 + original bytes)
so the existing PDF processing and checksum skip work unchanged. Normal HTML pages are
continued immediately, no measurable difference in fetch time.

* Fetchers - Add supports_pdf capability, only force html_requests for PDFs when the fetcher can't supply them

PDF watches were always forced onto html_requests. Now that puppeteer can capture the original
PDF (useful when the session needs a real browser, Cloudflare etc), only fetchers without
supports_pdf fall back - both at fetch time (resolve_content_fetcher) and in Watch.get_fetch_backend.

Also save the content-type when a fetcher couldn't supply the PDF (it was only saved on success),
otherwise watch.is_pdf never became true for URLs not ending in .pdf and the watch failed on
every check instead of falling back to html_requests on the next one.

Several places call gc.collect() after a check to keep C-level memory
(pyppeteer buffers, libxml2 documents, PIL, brotli) from accumulating.
Individually each is reasonable; run concurrently by many fetch workers they
become a storm. Every gc.collect() is a full stop-the-world pass that walks the
whole heap holding the GIL, so at FETCH_WORKERS=50 the process spends most of
its time stopped in the collector - which also starves each worker's asyncio
loop, leaving its CDP websocket unread.

Measured on 153 real puppeteer checks of a live site at FETCH_WORKERS=50, with
an `//div` include filter so the lxml document tree is realistic:

                     collects  objects freed  gc time  checks/sec  CPU/check     RSS
  one per call site       790      2,594,098    91.3s       0.766     1.373s  279.6MB
  debounced to 1s          48      2,219,010     7.3s       1.433     0.731s  275.3MB
  none at all               0              0     0.0s       1.503     0.685s  287.7MB

Debouncing keeps 86% of the reclamation for 6% of the collections: 1.9x the
throughput, half the CPU per check, gc down from 30.8% to 6.4% of wall time,
and a lower resident plateau than collecting every time. It works because the
collector is process-wide - any worker's collection breaks every other worker's
cycles too, so with many workers the calls are overwhelmingly redundant
duplicates rather than independently necessary.

Removing them entirely is slightly faster still, but it was the only
configuration whose RSS had not plateaued by the end of the run, so it is not
the default. EXPLICIT_GC_MIN_INTERVAL=0 restores the previous behaviour.

Collecting a younger generation was measured and rejected: gen 0 freed 1,136
objects against the full pass's 2,594,098, because objects surviving a 10-30s
fetch have already been promoted out of gen 0.

Two call sites are additionally fixed because they could never reclaim anything:

- Watch.py brotli: brotli.Compressor is not gc-tracked, so the collector cannot
  see it - `del` frees it by refcount. Over 60 x 2.2MB compressions, RSS growth
  was +0.9MB with neither mechanism, +0.2MB with gc.collect() alone, and +0.0MB
  with malloc_trim() alone or with both. malloc_trim is the load-bearing line
  and is kept; the collect cost ~31ms of stop-the-world per snapshot save for no
  reclamation.

- puppeteer quit(): runs twice per check (run()'s finally, then the worker's
  safety net) and nulls self.page/self.browser in its own finally blocks, so the
  second call closes nothing and breaks no cycles yet still paid for a full
  collection - 88 calls across 51 checks. Now only collects when it actually
  closed something.
