ozymandiashh 7be5a69c87 fix(optimize): one junk vocabulary for the count, the trend and the display
detectJunkReads took its count from core's detector and re-derived its display
and trend from the host's own JUNK_DIRS regex. The two lists disagreed: core
classifies `vendor`, `site-packages`, `out` and `target` as junk; the host's
did not.

Core was already counting reads under those segments — the count is not what
was wrong. The host's derivation was. In a repo whose junk reads all live under
one of them — Go and PHP vendor, Python site-packages, Rust target, Java or
Next out — the host loop matched nothing, so `recentJunkReads` stayed at zero.
Where the window also had recent activity, `computeTrend` read that as fixed
and returned 'resolved', and the finding was dropped. Whole ecosystems never
saw it. In mixed repos it survived but rendered incoherently: the explanation
quoted core's total while the directory list and the CLAUDE.md suggestion came
from the narrower host counts, so the numbers did not add up and the suggested
directories omitted the one actually causing the waste.

Core now exports `junkSegmentOf`, which returns the exact segment that made a
path junk. The host deletes JUNK_DIRS and JUNK_PATTERN outright and asks core
in both loops — junk-reads and duplicate-reads, which had the same split. The
host still names the directory for the payload, because a class alone cannot
render `vendor/ (5x)`; it just no longer decides what junk means.

Inside core, the precedence rule (dependency > build > vcs) lived in the order
of three loops, and adding junkSegmentOf duplicated them. Both functions now
consult one private helper, so the two cannot drift — a second copy of one rule
is what caused this bug in the first place.

Two display changes fall out. A path under two junk segments of the same table
now names the first in path order rather than the first in array order, so
`/x/build/dist/y` reports `build` where it used to report `dist`; the count is
unchanged. Terminal junk directories and Windows-style paths are now matched,
which the old slash-delimited regex missed — those align the host with what
core was already counting.

One robustness note: the old `JUNK_PATTERN.test()` coerced a truthy non-string
`file_path`, while `junkSegmentOf` would throw on one. The type is narrowed at
the point of use so the new path cannot throw where the old one could not.
