D348: mini slider glyph beside the file-select PC Options label

No settings icon exists in the game art (mainfolderimages holds only
copy/del/select-arrow/X/check/dot), so a miniature slider control is drawn
instead: three menu-box tracks with offset knobs in the 14px gap after Erase
(10px wide, 2px margins), INK_DIM tracks, knobs matching the label ink
(white / gold while hot). Tracks the dynamic label x (JP-safe), text position
unchanged; hot region extended to include the glyph. PCDUMP pixel-verified.

+## D348 — File-select "PC Options" label gets a mini slider glyph (2026-09-27)
+
+User request: an icon next to the "PC Options" bottom-bar label, like Copy/Erase
+have theirs. There is no settings-style sprite anywhere in the game art — the
+`mainfolderimages` bank (`assets/oddtextures.h:57-64`) holds exactly six:
+COPY, DEL, SEL (select arrow), X, CHECK, DOT. Per user choice, a glyph is drawn
+instead of borrowing an off-meaning sprite.
+
+Implementation (port-only, `optionsFileSelectLabel()` in frontoptions.c):
+three 2px menu-box tracks with offset 3×4 knobs (a miniature slider control),
+emitted with the same `microcode_constructor_related_to_menus` primitive the
+options screen uses for its slider bars. Tracks are `INK_DIM`; knobs match the
+label ink (white, gold while hot). The glyph is 10px wide (`GLYPH_W`) and sits
+INSIDE the existing 14px `LABEL_GAP` after Erase (2px margins each side), so it
+tracks the dynamic label x — JP's wider Erase pushes glyph + label together —
+and the text position / right-edge clearance are unchanged. The hot region
+extends left to include the glyph. No new strings (issue #87).
+
+**Verification:** `build-pc.sh ntsc-final` clean; headless file-select capture
+(`GE_STARTMENU=5 GE_PCDUMP=200-201`, 1088×816 = 440×330 canvas × 2.473): the
+glyph box (logical x 339–351, y 278–292) contains 135 pure-white pixels — the
+three knobs — vs 9 on an equivalent empty-paper strip. Visual feel-check owed
+to the user (proportions/knob offsets are one-constant tweaks if it looks off).
