Greptile Summary

This PR consolidates the two icon fonts (icons.ttf + li-icon.ttf) into a single updated icons.ttf, removing the separate .licons CSS class and migrating all usage sites to the unified .icon class. It also fixes icon sizing inside dragged tabs, restores inline alignment for plugin meta icons, and adds an Icomoon project file for easier future icon management.

Key changes:

• src/res/icons/style.css: Removed @font-face for li-icon, removed all .licons.* rules, added the merged glyphs (zap, verified, terminal, tag, scale, cart, lightbulb, pin, pin-off, square-terminal, and more) to the .icon.* namespace with a cache-busting ?v2 query string
• All callsites (codeActions.ts, lspInfoDialog, terminalManager.js, editorFile.js, selectionMenu.js, main.js, mainSettings.js, plugin.view.js, plugins/item.js, file-menu.hbs, menu.hbs, openFolder.js) migrated from licons xxx to the correct format for their rendering context
• src/components/tile/style.scss: Added .file, .icon size rules inside &.drag to keep dragged-tab icons at the correct 24 × 24 px size
• src/pages/plugin/plugin.scss: Moved inline-flex / align-items to the parent .meta-item and added flex-shrink: 0 to nested .icon elements, restoring visual alignment in the plugin detail page
• utils/code-editor-icon.icomoon.json: New Icomoon project file committed for easier future glyph additions
• src/res/icons/li-icon.ttf: Font file is no longer referenced but remains in the repository

Confidence Score: 5/5

Safe to merge — all remaining findings are minor style/cleanup suggestions with no runtime impact.

No P0 or P1 issues found. The icon migration is thorough (zero remaining licons references in src/), glyph codepoints are consistent between style.css and the updated font, and the two rendering-context patterns (full class string for direct className vs. bare name for components that prepend "icon") are applied correctly across all callsites. Only two P2 items: a pre-existing inconsistency in getCodeActionIcon's fallback string format, and the dead li-icon.ttf binary file still in the repo.

No files require special attention; src/cm/lsp/codeActions.ts has a minor cosmetic inconsistency worth a one-line fix.

Important Files Changed

Filename	Overview
src/res/icons/style.css	Removed the separate li-icon @font-face declaration and all .licons.* classes; merged glyphs into icons.ttf under unified .icon.* selectors. Cache-busting query string updated to ?v2. Glyph codepoints for scale and lightbulb changed (swapped relative to old li-icon.ttf) — consistent with the new font layout. Several new glyphs added (square-terminal, funnel, user-round, house, etc.).
src/cm/lsp/codeActions.ts	Updated fallback icon class from "licons zap" to "icon zap". Minor inconsistency: CODE_ACTION_ICONS entries use bare names (e.g. "build") while the fallback includes the "icon" prefix, resulting in class="icon icon zap" when rendered through select.js. Functionally fine (selector still matches) but inconsistent.
src/components/tile/style.scss	Added .file, .icon size rules (24px × 24px, font-size: 1em, flex-shrink: 0) inside the &.drag context so that icon-based tab icons (now using .icon instead of .licons) are correctly sized in dragged tabs.
src/components/terminal/terminalManager.js	Updated terminal tab icon from "licons terminal" to "icon square-terminal". Uses the new square-terminal glyph added to icons.ttf, correctly passed as a full class string for direct className assignment.
src/lib/openFolder.js	Both context menu "Open in Terminal" entries updated from "licons terminal" to "terminal". Correct — select.js prepends "icon " to produce class="icon terminal", matching the new CSS definition.
src/pages/plugin/plugin.scss	Restructured .meta-item to include display: inline-flex; align-items: center; gap: 4px; vertical-align: middle (previously only on .author-name), and added flex-shrink: 0 for .icon inside it. Restores inline alignment for plugin meta icons.
src/settings/mainSettings.js	Updated icon values from "licons terminal" / "licons zap" to "terminal" / "zap". Correct — settingsPage.js wraps these as class="icon ${item.icon}", consistent with all other icon entries in this file.
src/views/file-menu.hbs	LSP info menu item icon migrated from <span class="licons zap"> to <span class="icon zap">. Matches the new unified icon class system.
src/views/menu.hbs	Terminal menu item icon migrated from <span class="licons terminal"> to <span class="icon terminal">. Correct.
utils/code-editor-icon.icomoon.json	New Icomoon project file attached for maintainability; allows future icon additions via the Icomoon web app. No code impact.
