The #95 telemost fix widened three global windows (control pong 15s->45s,
smux keepalive 30s->120s, tunnel ack 15s->90s). These live in shared
packages, so they also slowed dead-link detection on jitsi/datachannel:
a genuinely dead session stayed alive up to 120s before reconnecting,
which presented as the link going down and not recovering.
Restore the conservative defaults globally and apply the relaxed windows
only when the transport implements transport.ControlPlane (vp8channel/
goolom), where KCP batching + SFU publisher-PC renegotiation legitimately
go silent for ~25-30s. Conventional carriers reconnect promptly again.
Video-paced transports (vp8channel, videochannel, seichannel) need
longer operation timeouts due to frame pacing and KCP batching:
- streamPatternForDuration: 15s -> 60s for video transports
- sustainedEcho: 5s -> 60s for video transports
Part of fix for issue #95.

Address 25 issues reported by golangci-lint following the structural
refactor:
- cyclop: split common.Reassembler.Push into upsert/storeChunk/deliver
helpers (12→5). Move seichannel option-default fill into Options.
withDefaults so New stays under the limit.
- exhaustive: enumerate ResultPartial / ResultIgnore explicitly in
seichannel and videochannel switches over common.Result.
- gosec G115: annotate the test-fixture int→uint16/uint32 conversions
in common_test.go with //nolint:gosec.
- lll: break up the 130+ character one-liners in transport
unit/integration tests and the videochannel track-ID construction.
- nolintlint: drop the stale //nolint:cyclop in mobile_test.go where
the underlying complexity already cleared the limit.
- wrapcheck: wrap errors returned from internal/framing and
internal/runtime in their public callers (handshake, control,
server.setupCipher, client.setupCipher) so they carry the layer name.

handshake and control duplicated the same 4-byte BE length + body framing
with independent ErrFrameTooLarge constants. Centralize in internal/framing
and have both callers delegate. ErrFrameTooLarge is re-exported so existing
errors.Is checks keep working.
