fix(emcn): normalize the folder icon family to the house geometry

[waleedlatif1]

Folder and FolderCode both carried a fill-based construction in a tight viewBox with a hairline stroke, while FolderOpen was the house-standard stroke outline. Measured at size-[14px]:

icon	glyph	stroke
standard (pencil)	10.8px	0.90px	baseline
folder-open	10.9px	0.90px	✅ already correct
folder (before)	20.6px	0.28px	❌ ~2× size, ⅓ weight
folder-code (before)	19.9px	0.28px	❌ ~2× size, ⅓ weight

Both now measure 10.1px / 0.90px.

Why it was visible

• Folder vs FolderOpen toggle in place in the sidebar folder rows — expanding a folder visibly shrank its icon.
• FolderCode renders in Chat's TOOL_ICONS map for glob/mv/mkdir, directly beside standard-geometry Search, File, and Database.

Neither appeared before the lucide migration — lucide shipped all three as matched 24-boxes.

Fix

Folder is redrawn as FolderOpen's own body outline closed along the bottom-right; FolderCode reuses that body path byte-identically and insets code brackets centred on the body (x 9.125, y 11.25). The family now shares one silhouette and one weight by construction.

Call-site safety

Changing a viewBox is never a one-file change. All 19 <Folder> and 4 <FolderCode> sites audited:

• Explicitly sized — all square; none sized to the old 14.5:13 / 15:13 aspect, so nothing letterboxes.
• Unsized (7 Folder) — all inside DropdownMenuItem or SettingsResourceRow, which force-size via [&_svg]:size-[14px], absorbing the intrinsic change.
• FolderCode consumers (agent-group, FeaturePlatformPanel, agent-code-graphic) all pass an explicit square size-*.

Deliberately not changed

• connections (21.5px / 0.22px) is the same class, but it is a filled glyph for Integrations — correcting its size is mechanical, converting it to a stroke outline changes its character. Wants its own design call.
• zoom-in/zoom-out/undo/redo measure 0.99px stroke vs the 0.90px standard — within tolerance, not worth churning.
• play is deliberately filled; PlayOutline is its stroke counterpart and is what TOOL_ICONS already uses.

Unrelated finding (not addressed here)

TOOL_ICONS (message-content/utils.ts) has 73 keys mixing agent names with tool names, but its sole consumer getAgentIcon(agentName) is only ever called with sub-agent names. The tool-name subset appears dead. Worth a separate look — either the map should be pruned, or per-tool icons were meant to render somewhere and don't.

PR Summary

Low Risk
Single icon asset change in emcn with no logic or API changes; visual-only risk is consistent sizing at existing call sites that already use square dimensions or parent-forced SVG sizes.

Overview
Redraws the Folder icon so it matches FolderOpen when sidebar folder rows toggle between closed and open states.

The closed folder moves from a small filled outline (14.5×13 viewBox, thin stroke) to the same 24×24 canvas, viewBox='-1 -2 24 24', stroke-only rendering, and strokeWidth='1.55' as FolderOpen, using a path derived from the open icon’s body closed along the bottom-right. That removes the visible shrink/grow when expanding a folder under square sizing (e.g. size-[16px]).

Documentation in the component explains the pairing intent for future icon work.

Greptile Summary

This PR redraws the closed Folder icon to match FolderOpen when toggled in place.

• Aligns both icons on the same 24×24 viewBox and intrinsic dimensions.
• Replaces the filled outline with matching stroke geometry, weight, and line caps.
• Preserves caller overrides by applying SVG props after the defaults.

Confidence Score: 5/5

The PR appears safe to merge, with the Folder geometry consistently aligned to FolderOpen and existing call-site sizing preserved.

The changed SVG uses the same viewport, dimensions, stroke defaults, and body silhouette as FolderOpen, while current callers constrain sizing and do not depend on the former fill or stroke attributes.

Important Files Changed
