Upstream returns 400 INVALID_ARGUMENT when toolConfig is absent. The guard
`if !isReasoning || len(tools) > 0` skipped it for reasoning models called
without tools, contradicting the intent stated in the comment above it.
Set toolConfig unconditionally and cover the three cases with a unit test.
Long-running LLM inferences (such as high-thinking Gemini models) may experience
silent TCP disconnections across intermediate proxies, NAT gateways, or firewalls
when no data frames are emitted for tens of seconds to minutes.
Go's default http2.Transport sets ReadIdleTimeout=0 (disabling active PING checks).
This commit introduces HTTPUpstreamProfileLongStream with:
- ReadIdleTimeout = 10s
- PingTimeout = 5s
When a pooled H2 connection stays idle for 10s during long streams, active PING frames
are dispatched. Dead connections failing to respond within 5s are proactively evicted,
preventing client generation requests from hanging on dead sockets or failing with EOF/502.

When running a custom build or pre-release version (e.g. v0.1.183-custom),
parseVersion failed to parse the patch segment because of the non-numeric suffix,
causing compareVersions to incorrectly report an available update.
This commit strips any hyphenated suffix before splitting SemVer components.
