spec: gate-119 procedure-named-classes (ADR-118)

[rubenvdlinde]

Spec for gate-119 procedure-named-classes, which enforces ADR-118 (ConductionNL/hydra#749, decisions 182 and 185).

What the gate will do

• It counts files under lib/ and src/ whose path carries a procedure token (woo, bezwaar, beschikking, termijn and so on). JSON, lib/Settings/, lib/Migration/ and src/manifest* are not counted, because configuration is where a procedure name belongs.
• A per-app allowlist baseline .hydra/procedure-names.json names today's files. A new procedure-named file that is not on it fails.
• The head count may not exceed the base-ref count. A stale baseline entry therefore cannot let a deleted file come back.
• Standards-named files (ZGW, StUF, BRP, KvK, DSO and others) are reported as a warning in a leaf app. They are never refused, and the warning names integriq or filinq as their home.
• --write-baseline and --shrinkable modes, plus a reason-bearing @procedure-name exclude marker.

Numbers at adoption

App	Procedure	Standard
dossiq	229	109
humaniq	8	1
shillinq	8	18
learniq	5	0
pipelinq	3	30
portaliq	3	0
filinq	1	1
decidiq, openregister	0	0 and 4
integriq	0	127

Notes

• The number 119 is taken because gate-117 is feat(hydra-gates): gate 117 reads PHP and schema strings as missing, not only as unused #782 and gate-118 is feat(hydra-gates): spec-screens gate #836.
• This repo has no development branch, so this PR targets main.
• This is the spec only. Building is a separate step: refactor lane R10.
