catarrh cc480c30b7 v3.13.3: ELF version retry for both P1 values + query-based per-AID budget
elfTagListRetry walks the untried tag-list forms for P1=10 and P1=20
(skipping combinations the main pass already refused via the expandedTried
map; only the tag-list forms are retried - the no-tag-list form never
carries CE - and the walk stops as soon as a version appears).  The form
memory can skip the tag-list forms for P1=10 when the Apps listing served
only the no-tag-list form (live 2026-10-02: EP BAP - its P1=10 tag lists
were never queried while the P1=20 retry refused them).

elfPerAidVersions filters to packages that actually have an applet
candidate before the six-query cap: the budget counts queries, not list
positions (EP BAP's first six packages are Oracle/JC-API entries with no
app instances - they consumed the cap and the A113 packages were never
queried).

Docs: help EN/RU, repo AGENTS (v3.13.3 note).  sw cache simple-v373.
Tests: 667 Python + 796 frontend green.
