fix(install): install.sh takes --option value, exits with a status for each cause, and narrates and traps with Declare-BashScript's functions - #1039

…re-BashScript's functions (#1037)

Phase 3 of lanes 62 and 64 of #916. scripts/Test-InstallScript.sh and
packaging/macports/generate-portfile.sh carry the helper's note, success, error, on_error_or_interrupt and Set-Traps,
byte-identical to NobleFactor/noblefactor-ops c942f54's, with the exit statuses each uses, copied by hand: nothing
sources or embeds the helper, as the owner ruled 2026-10-09 and 2026-10-10. Each keeps its own option parsing, so
each runs where it runs today, and CI stays as it is.

The suite reports each check in the helper's form and exits 1 when one fails, 64 on a usage error, 66 when
DEVLORE_TEST_DIST lacks this platform's archive, and 70 when make dist fails; its trap is Set-Traps with a cleanup
that removes its scratch directory. Its 13 old lines over 120 columns are wrapped, every string they hold unchanged;
one line of fixture data, GitHub's own rate-limit message, stays as GitHub sends it. It passed all 249 checks on this
Mac, install.sh under macOS's own bash and tools. generate-portfile.sh wrote the Portfile for
v0.1.0-dev.20261005182840.

The plan records the rulings and the approval: the generator, pin and drift check are gone, the two tools carry the
helper's functions rather than the helper, the CI change it needed is moot, and phases 1 to 3 are ticked. The
command-line design says install.sh carries copies of the helper's functions, made by hand, and section 9 names its
exit statuses.

…s, and takes both option forms (#1037, #1038)

Phase 4 of lanes 62 and 64 of #916. install.sh carries the helper's note, success, error,
on_error_or_interrupt and Set-Traps, as NobleFactor/noblefactor-ops c942f54 has them, copied by hand, with the six
exit statuses it uses: it sources nothing, carries none of the helper's checks for bash 5.3 or GNU getopt, and runs
with what ships with macOS. Its narration moves to stderr in the helper's form, its warning is error 0, and each
refusal exits with the status of its cause, as ruled 2026-10-09: 64 a usage error; 65 an archive it cannot verify; 69
a missing tool, or GitHub refusing a request, serving a file by another name, or lacking the release; 70 a failed self
install; 75 GitHub's spent rate limit; 78 an unsupported platform.

Each of --prefix, --base, --team and --personal takes its value as --option value or as --option=value, and one given
last with no value is refused by name with 64 (#1038), in a loop that runs on bash 3.2. The usage says both forms and
the statuses.

The suite's refusals each expect their status, and it passed all 249 checks on this Mac, install.sh under macOS's own
bash and tools; under /bin/bash 3.2.57 and bash 5.3.20 alike, install.sh refuses as it should. The plan ticks phase 4,
separates its table of statuses from the paragraph after it, and names a file served by another name under 69.

…stall.sh exits with (#1037, #1038)

Phase 5 of lanes 62 and 64 of #916. scripts/Test-InstallScript.sh now checks each of
--prefix, --base, --team and --personal given last with no value, refused with 64 by name before any download;
--base in the space form; an architecture other than amd64 and arm64, 78; a self install that fails, 70, under a
prefix whose bin is not writable, as /usr/local/bin is without sudo; an archive with no program DEVLORE_TOOLS names,
65; and --prefix, --personal and --team in the space form installing and registering what the = form does, and
--prefix= too. Every message it checks is matched in the helper's form, note's, success's or error's. It passed all
288 of its checks on this Mac, install.sh under macOS's own bash and tools.

The getting-started guide shows both forms of each bash flag, and its install command is wrapped to 120 columns. The
command-line design's section 2 says install.sh takes both and refuses a value-less option by name, and its status
page records the revisions of sections 2 and 9. The plan ticks phase 5, lists the two documents, and shortens its
title to 110 columns: at 147 it broke the 120-column rule, reported as anthropics/claude-code#101106.

…e 7 close with the pull request (#1037)

The suite passed all 288 checks on this Mac with macOS's own tools and with MacPorts', and on danoble-ud24-1.local
against this branch's linux/arm64 archive; install.sh, piped into bash there under a scratch HOME, installed the newest
release and registered nothing; and under danoble-wd11-3's Git Bash it refused a value-less option and the platform.
The next devlore-cli pull request ticks the CI box and phase 7, as plan 289's were.
