SnapOtterandGitHub d10d0f544f fix: release QA hardening across processing, media, security, and CI gates (#649)
A release-readiness QA pass over the whole product. The commits split into
defects a user would hit and gates that were reporting green while measuring
nothing.

## Fixes that change behaviour

Rate limiting was bypassable on every install: TRUST_PROXY defaulted to true, so
request.ip came from a client-set header and a forged X-Forwarded-For got past
the login limiter. The default is now a private-network trust list.

A transient Postgres outage stranded in-flight jobs, leaving finished output on
disk with no row pointing at it. A reconciler now resolves those rows and adopts
the bytes rather than dropping the work.

A Redis connection that moved to a new address wedged every read-blocked
consumer, so completions stopped signalling while health still answered 200.
Socket timeouts plus subscriber pings recover it.

Installing more than one AI bundle left the shared venv multi-versioned and
silently broke three tools. The installer now reconciles distributions to one
version each.

Converting an image to JXL at quality 1 through 4 returned a 500, because
libjxl 0.7 rejects the distance those values compute. The quality is floored at
what the encoder honours. A missing ffmpeg was also reported to the user as a
corrupt upload; it now says the engine is unavailable.

RAW uploads reached an unpatched LibRaw on arm64, so it is built from source at
0.22.2, and the release scan was split so it can fail on an unfixed critical
instead of hiding it behind ignore-unfixed.

## Gates that could not fail

Two mutation lanes ran zero mutants because Stryker crawled the gitignored docs
build; coverage discarded its whole report on any failing test; the lint gate
skipped root tests, scripts, and two workspaces; and several generated matrices
counted a host missing ffmpeg as a passing tool. Each now measures what it
claims.

Full evidence and the outstanding release items are tracked locally and are not
part of this branch.

"""Regression reproduction for the shared-venv version conflict (AI-20260726-001).
`reconcile_onnxruntime` fixed exactly one package pair. Every OTHER distribution
that two bundles both provided was merged by `move_tree` file-by-file, with no
uninstall of the version already in the venv, so two versions ended up overlaid:
the pure-Python modules came from whichever bundle wrote last while the compiled
extension CPython actually imports could come from the other.
Observed live on ubuntu-gpu-amd64 after Settings > AI Features > Install All:
seventeen distributions carried two or three versions at once. Three of them
broke a tool.
tokenizers 0.20.3 (inpaint-hq, pinned by transformers 4.46.3) and 0.23.1
(transcription, needed by faster-whisper) both present. The package directory
held tokenizers.cpython-312-x86_64-linux-gnu.so from 0.20.3 next to
tokenizers.abi3.so from 0.23.1; CPython prefers the platform-specific suffix,
so 0.23.1's `decoders/__init__.py` ran against 0.20.3's binary and raised
"AttributeError: module 'decoders' has no attribute 'DecodeStream'". The
transcription install failed its own smoke gate and could not be installed at
all on that host.
scipy 1.12.0 and 1.17.1 -> Real-ESRGAN cannot import, `upscale` fails.
huggingface_hub 0.36.2, 1.19.0 and 1.22.0 -> transformers refuses to import,
the high-quality Object Eraser path fails.
The invariant is deliberately modest and does not presume a particular winner:
after a bundle's site-packages has been merged into the venv, exactly ONE
version of any given distribution remains, and no file belonging to the
superseded version survives to shadow it.
