jatmnandClaude Opus 5.5 e3aee00e9d ci: feed ci-surfaces NUL-delimited paths and pin its mapping in a test
The mapper read newline-delimited `git diff --name-only` output. In that
mode git C-quotes any path with non-ASCII, tab, double-quote or newline
characters, so crates/gl/src/é.rs arrived as "crates/gl/src/\303\251.rs",
matched no surface, and a PR whose only Rust change was such a file ran no
Rust job (Café.swift likewise skipped Swift CodeQL). Newline-delimited
input also cannot carry a path that contains a newline.

Both workflows now pass `git diff -z` output and the mapper reads it with
`read -r -d ''`; input that is not NUL-terminated is rejected (exit 2)
instead of being misread. Mapping output for every ASCII path is
unchanged (checked against the last 43 commit ranges).

scripts/test-ci-surfaces.sh pins one must-not-skip case per surface row,
the crate fan-out and widening rules, --all, the wiring rows, quoted
names, and rejection of newline-delimited input. PR Checks runs it in the
`changed surfaces` job before mapping, on every event, so a broken mapper
turns the run red rather than silently narrowing it.

# Advanced-setup replacement for CodeQL default setup. Default setup analyzes
# every detected language on every PR, including Swift (macos-app/), which
# autobuilds on a macOS runner for ~13 minutes per PR and has hung for 55 on
# main; that single job was the longest check on most PRs. Here a PR analyzes
# only the languages it touches (scripts/ci-surfaces.sh), while push to main
# and the weekly schedule analyze every language, so main's code-scanning
# baseline stays complete.
#
# Requires CodeQL default setup to be DISABLED (Settings -> Code security ->
# Code scanning): GitHub rejects advanced-setup uploads while it is enabled.
#
# A PR that skips a language may show "configuration not found" on the CodeQL
# check for that language; that is informational and expected.
