feat(performance): add Eskay's config and stop collapsing RenderModes

[Slush97]

Eskay's config

Sqooky added Eskay's config/ to OptimizationLock on 2026-10-05 ("minor fork of Sqooky's with tweaks to suit her preferences"). It is Sqooky's default without the far-clip and fade-distance culling (r_farz, r_mapextents, sc_fade_distance_scale_override), so buildings and players don't pop in, plus props_break_max_pieces_perframe 1 and a 2.2 aspect-ratio opt-in.

• New preset eskay under a new Light tier (card titles are tier labels, so sharing Balanced would show two identical cards). Sorts right after Sqooky's Balanced, which stays first.
• OptimizationLock 3.4 pin moves from 2b994f62 to e2e9925c. The commits in between only reformatted the bundled files (zero key changes through the generator) and added Eskay's file; upstream still states 3.4. 3.4 has not shipped in a release yet.
• Generator: a preset may record null sha256 for older releases where its file did not exist yet. Only a trailing run of older releases may be null; a null at the newest release fails loudly (file moved or deleted).
• Avatars bundled for Eskay and kaizuchanerus (50x50, like the existing two).

RenderModes fix

MaterialSystem2/RenderModes in stock gameinfo.gi is a list of seven game entries; City Never Sleeps added ShadowSilhouette. The parser keeps the last duplicate, so configs written before that (boot, OptiLock 4.6/5.0/5.1) diffed to game "FrontDepth", and applyOp edits every occurrence, collapsing all seven render modes into FrontDepth.

• On main since chore(performance): refresh presets to OptimizationLock 3.4 and OptiLock v5.1 #418 in 6 bundled bodies (unreleased).
• Live in v1.30.x for track-latest users applying boot or OptiLock, because the runtime diffs against the current upstream baseline.

Fix: exclude the section in the manifest, and have latestAsPreset re-apply today's section exclusions to cached bodies, since a cached track-latest entry is reused while upstream and baseline commits are unchanged. Already-affected files are restored on the next reapply or preset switch (removal works from the markers). In-game effect of the collapsed list was never tested.

Testing

• pnpm typecheck, pnpm lint, pnpm ui:check, pnpm i18n:check, pnpm i18n:manifest --check, pnpm perf:presets --check
• vitest: 181 files pass. Two new tests (generator ignores a list-valued RenderModes; cached body with a RenderModes op is filtered) fail without the fix.
• Regenerated data diff vs pre-fix: only the 6 RenderModes ops removed plus the new exclusion entry.
• Viewed the Performance settings page in a built app: Light card with Eskay's avatar, kaizu's avatar on Potato.
