fix(portal): PML range ops are INCLUSIVE; a stalled import body can no longer wedge the Add form

The 20-mod sweep ("test every pml mod") found two real bugs and one open
defect.

INCLUSIVE RANGES: PolyTypes.js's own doc comments say "Replace code between
2 given tokens. Inclusive." — the anchors are replaced along with the span,
and every real mod's func only makes sense that way. Ours kept the anchors,
so carswitcher's twin splice on "models/car.glb" (func:
window.localStorage.MyCar || "models/car.glb") produced two adjacent
expressions — a syntax error the re-parse gate turned into base-failed. The
first full-library attempt died exactly there. With the fix the same mod set
boots planStatus: applied and the car-model twin is 1/3 (the other two
anchors genuinely match 0 on main; one targets 604.bundle.js).

BODY-READ TIMEOUT: fetchText cleared its 20s abort timer when the response
HEADERS arrived, so a body that never finished streaming hung the import
promise forever — no error, no row, the Add form silently wedged on one bad
CDN connection (observed live). The timer now covers headers through body;
a stalled stream fails as "timed out".

THE OPEN DEFECT (documented in progress.md, not fixed here): sequential
installs stall from the fifth — sometimes writing storage without updating
the library count, sometimes never settling. Solo installs of the same mods
work (ghosttoggle's real id is mrgtmod — two harness generations died
waiting for catalog slugs that never exist as installed ids). Suspect: the
page's import → updateUserMods → refreshRunningSet reload-chain interplay.
Also noted: xenon installs but never loads.

Portal 735 -> 740 tests (inclusive expectations, carswitcher's
distinct-anchor shape, the fetchText body-timeout suite); repo-wide 1,352
green; smoke:pml PASS; smoke typecheck after the last script edit.
