Brings the Go hub and web SPA work developed on feature/udpscope onto
main, without the udpscope client itself.
The trigger engine could not capture a sporadic event: it armed on the
live tail only, so a burst shorter than one push window was already past
by the time the FSM looked for it. It now searches the ring history for
the crossing, which also makes a capture reproducible from the same data
rather than dependent on push timing (wshub/trigger.go, ringbuf.go,
history.go).
Adds CSV/JSON export of the visible window (wshub/export.go) and reworks
the SPA: per-signal axis controls, a readable trigger panel, and a fix
for the flicker caused by repainting on every push instead of on a frame
tick (static/app.js, index.html, style.css).
BUFFER_AND_TRIGGER.md documents the ring/decimation/trigger interaction,
which is otherwise only inferable from the three files that implement it.

- 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

Renames the "Add Source" section to "Sources & Config" and replaces the
fire-and-forget "Save list" button with Save and Reload, plus a one-line
status area that renders the hub's configSaved/configReloaded ack.
onConfigAck replaces the no-op stub Task 7 left behind. It branches on the
frame type because configSaved carries a path and configReloaded does not,
and surfaces the hub's error text on failure rather than failing silently.
The status is kept outside the DOM because buildSidebar() recreates this
section on every sources broadcast.

Finding 1: revert the comma/quote strip added in 3cb998c from
normaliseCal() in calibration.js. The strip broke byte-identical parity
with Go CalConfig.Normalise and C++ StreamHub::SetCalibrationEntry, both
of which only trim whitespace and cap at 16 UTF-8 bytes. Delete the
companion test that asserted the now-removed behaviour (suite returns to
18 tests).
Finding 2: fix the actual CSV-safety problem at the point of use in
exportAllCSV() in app.js. Header cells (time column and signal columns)
are now RFC 4180-quoted: wrapped in double quotes with any embedded
double quote doubled. This safely handles units or signal names that
contain commas or quotes without touching normaliseCal.
Finding 3: update two stale comments in app.js that called the trigger
threshold or rawFromNorm result 'raw' — Task 9 moved trig.threshold into
calibrated units throughout, so the comments now say 'calibrated'.

refreshVScaleMenu() was unconditionally removing the cal-invalid class
from all three calibration inputs, which silently cleared the red-border
error indicator on a field the user was editing whenever a hub
calibration broadcast arrived. Apply the same focused-element guard
already used for .value writes so a rejected value's error styling
persists until the user corrects it.

Adds the Cal row (Scale / Offset / Unit / Reset) to #vscale-menu, its
CSS, and the refreshVScaleMenu() / commitCal() logic that wires it to
calTable and the hub via setCalibrationWS.
