allocation, using io.LimitReader, while retaining the existing oversized-file
detection behavior. Add a regression test covering a local file larger than
maxBodySize.

selected path is a regular file before calling os.Open or io.ReadAll, rejecting
FIFOs and other non-regular paths so the local fetch cannot block before context
cancellation applies.

Inline comments:
In `@internal/modeldata/fetcher_test.go`:
- Line 425: Move the FIFO-dependent test using syscall.Mkfifo into a
Windows-excluded test file or helper with appropriate GoOS build constraints, so
the symbol is not compiled for GOOS=windows while preserving the existing
runtime behavior on supported systems.
In `@internal/modeldata/fetcher.go`:
- Line 144: Update the catalog file-opening flow around os.Stat and os.Open to
avoid validating one path and then reopening it: use a platform-safe
non-blocking open strategy, validate the resulting descriptor with f.Stat(), and
only then read from it. Preserve the existing regular-file validation behavior
while ensuring replacement by a FIFO cannot block the refresh path.

Summary
Two things an air-gapped operator needs from core, plus a doc correction.
GOMODEL_OFFLINE=true(offline: trueinconfig.yaml) is one switch that disables every outbound call the gateway makes on its own: the update check and the remote model catalog download. It is applied after every other config source, so neitherconfig.yamlnorGOMODEL_VERSION_CHECK_ENABLED=truecan re-enable a call underneath it. Calls to configured providers and operator-declared endpoints (OTLP, MCP upstreams, vector stores) are untouched. Startup logs the mode. Default:false, nothing changes for existing deployments.MODEL_LIST_URLaccepts a local file. A bare path (/etc/gomodel/models.json) orfile://URL is read on startup and every cache refresh, and re-parsed only when its content changes (validator is a SHA-256 of the file, reusing the existing ETag path soNotModifiedshort-circuits exactly like a 304). A local file involves no network request, so it stays active underGOMODEL_OFFLINE=true. This lets air-gapped sites keep pricing and budgets without running an HTTP mirror.Doc fix.
docs/guides/production.mdxclaimed "no update check", but the version check ships enabled by default. The air-gap section now lists both outbound calls with their defaults, the single switch, and the three ways to keep pricing offline.Docs
