Consuming a UDPStreamer feed so far meant either linking MARTe2 (UDPSClient)
or writing Go (Common/Client/go/udpsprotocol). Common/Client/c fills the gap
for plain C/C++ integrators: two files depending on nothing but libc and BSD
sockets, covering the whole receive path — CONNECT, fragment reassembly,
CONFIG/DATA decoding with dequantisation, keepalives and silence-triggered
reconnect. No threads are spawned; udps_client_poll() does all the work and
runs every callback, so it drops into an existing event loop unsynchronised.
Verified against run_udp_producer.sh at 1 Msps: unicast (120 MiB, no loss) and
multicast with 12-fragment cycles (116k datagrams, no loss).

- calibration.js: fix baseSignalName('[0]') parity with Go/C++ (>= 0 not > 0)
- calibration.test.js: add assertions for '[0]' edge case in two existing tests
- app.js: remove stale typeof guard around refreshVScaleMenu (always defined)
- app.js: call refreshTrigThresholdField on trig-signal change (both assignment sites)
- index.html: drop maxlength='16' on unit input; normaliseCal is the sole enforcer
- configcheck/main.go: delete dead nextOneOf function (no callers)
- hub_calibration_test.go: delete orphaned waitBroadcast comment (function never existed)
- calibration.go: correct arrayIndexSuffix comment to document known Go/C++ difference
- Docs/StreamHub-API.md: add calibration entry count and unit byte limits to §5 table
- spec: fix configReloaded missing path field, '16 chars'→'16 UTF-8 bytes', StreamString→char[], chain scenario→configcheck program, four→five new frames

Wire five new WebSocket frames into hub.go: setCalibration (client→hub),
calibration (hub→client broadcast), reloadConfig (client→hub), configSaved and
configReloaded (hub→client acks with ok/path/error). Extend hubCmd with cal
field, add buildCalibrationMsg and buildConfigAckMsg builders, send calibration
on client connect, and run Save/Reload on separate goroutines to avoid blocking
the Run() select loop.

Finding 1: strip trailing [digits] array-element suffix from Signal so one
calibration entry covers an entire array signal, matching the C++ strchr
truncation and the JS equivalent.
Finding 2: after the 16-byte Unit truncation, drop any trailing partial UTF-8
rune so json.Marshal never emits replacement characters; keeps byte limit in
sync with C++ strncpy(u, unit, kMaxUnitLen).
