Read every number phploc counts, not the two the report was built on

[chr-hertel]

A measurement has sixty-two numbers in it and the report drew two of them; the other
sixty sat in the json blob a release carries and were a re-clone away from being read.
They are all in the chart now.

The catalog

Metric is 54 of those 62, each addressed by a slug (?metrics=complexity,loc)
rather than by the phploc key behind it, since the query string is a link people read -
plus what it is called, one line saying what it counts, the section phploc prints it
under, the whole it is partOf(), how far it is rounded, whether the report has an
opinion about its direction and whether it carries a risk band. Left out are the five
minimums (classCcnMin is 1 in 96% of twenty thousand releases), testClasses /
testMethods (always 0) and ccnMethods - all of them still in the measurement and
still in the raw output.

Measurement reads a stored blob through it, MetricSelection parses ?metrics= by
the rules the repositories of a chart already follow, and MetricCatalog hands the
whole thing to the browser so nothing about a metric is written down twice.

The blob stays a blob: the two promoted columns stay columns because the report is
sorted, ranked and trended by them in SQL, while the other sixty are read one release
or one line at a time and never ordered by.

A second metric is a tab

Not a second axis and not a second chart - colour already says which repository a line
belongs to and cannot also say which number it is, and two scales in one frame let a
crossing look like a statement when what crossed was the scaling
(Datawrapper,
Flourish; SonarQube caps a graph at
three measures for the same reason). Drawn one at a time in the same frame - same
place, same width, same years - two metrics are compared by switching between them, and
switching keeps the years the reader is in.

The tabs sit inside the chart panel, on the row under the repository chips, ending on
the hairline that closes the panel head - so the head answers the two questions about a
chart in the order they are asked: which repositories, and in which number. A single
metric is still a tab there; with nothing to switch to it is not a choice but the only
place the chart says what it is drawing.

Every metric of a chart travels with every release, so switching is a redraw and never
a request; adding one is the fetch, and a line already on the page is asked only for
the number it is missing.

Reading one release

The four figures over the release analysis are read in whichever metric the chart is
open on, so switching a tab re-reads the release. Under them the panel lists every
picked metric, and folded below it stands the rest of the measurement: all 54 numbers
in phploc's four sections, indented under the whole they are part of, with their share
and their change since the previous release, each name a button that draws it. That is
owner/repository/<tag>/metrics; the raw output next to it is the same measurement as
phploc printed it.

Rebased onto #43

The branch predates the editorial rework, so it was rebased onto it and the design
re-thought rather than merged hunk by hunk: the two-way segmented metric switch does
not survive 54 metrics, and the headline figures were hardcoded to complexity and LOC,
which say nothing when the chart is open on static method calls.

Carried along: the release rail keeps its tab for a single line too, a share written
under a figure that is itself a change now carries that change's sign, and
.tabs--series no longer reaches the one pixel past its row that gave a sideways
scrolling row a vertical scrollbar. CLAUDE.md catches up with #43 as well.

Checks

178 tests, phpstan level 8, php-cs-fixer, prettier, twig/yaml/container lint all green.
Driven end to end in a headless browser: tab switching keeps the years and drops the
y-zoom, adding from the box and from the measurement table both open the new tab, the
tab × removes, the query string round-trips, legacy ?metric=loc still opens what it
named, and the raw dialog still opens.
