llm-security-commons/lexicon/injection-lexicon.json
Kjell Tore Guttormsen 7b70f5b52f feat(lexicon): publish a commons-owned pattern id with per-runtime aliases 
A conformance fixture has to name a finding. The two runtimes that seed this
repository do not name the same pattern the same way -- llm-security says
"override: ignore previous instructions", the guard says
"override:ignore-previous" -- so until now no expected.json could be written
at all, including for the 64 patterns whose regex is byte-identical in both.

Each pattern now carries `id` plus an `aliases` object naming what each
seeding runtime calls it, and a top-level pattern_id_space block explains the
field, its provenance and its stability contract.

The id is adopted verbatim from the guard's port rather than invented here:
that port already carries both names, so the mapping is read from source data.
Matched by label <-> desc with em-dash normalised to hyphen, 83/83 one-to-one,
83 unique ids.

No detection data moved, and that is proven rather than asserted: labels,
patterns and flags are byte-identical in sequence, no flags key was invented
(78 before, 78 after), and stripping id + aliases + pattern_id_space
reproduces the previous committed file byte for byte -- 23566 bytes. All 83
patterns still compile in Node bare and under u (166/166) and in Python re
(83/83).

Neither consumer has ratified this id space; both were asked by coord today,
and the file records it as a proposal rather than implying agreement.
