app_icons: add the anvil glyph and register octoforge

OctoForge (~/octoforge) is app #10 in the shared launcher-icon family. It was
still shipping the stock Flutter icon, which is not a finished state.

The glyph is a filled silhouette rather than a stroked outline: a stroked
anvil is a long thin horn plus a narrow waist, and at the family's 72px stroke
weight the waist closes up solid at 48dp. An octopus (GitHub trade dress, and
a tangle of thin curves that blurs at launcher size) and a bare hammer (reads
as a generic tool, not a forge) were both rejected.

The horn is a separate wedge projecting off the face, not a rounded corner on
it. Two earlier drafts folded the taper into the slab's left end and both
rendered as a bump, leaving the shape reading as an I-beam. It now tapers to a
40px blunt tip, above MIN_NEGATIVE_SPACE so it survives at 48dp.

Registered with linux=True: unlike the other phone-first apps this one has a
real desktop target with a .desktop entry, so it needs the hicolor set.

Verified: generated for Android and Linux, checked against the family preview
sheet at all three sizes, and confirmed in the device app drawer next to todo.

Committed from a temporary worktree: the working tree held another session's
in-flight kuhylog entry in the same hunk, and git-rules.md forbids stashing
around other agents' uncommitted work. That work is untouched.

# A blacksmith's anvil: OctoForge is a GitHub client, and the forge is the
# name. Filled rather than stroked, for the same reason as the nib — a stroked
# anvil outline is a long thin horn plus a narrow waist, and at the family's
# 72px weight the waist closes up solid at 48dp.
#
# The obvious alternatives were rejected: an octopus (the Octocat) is both
# GitHub trade dress and a tangle of thin curves that blurs at launcher size,
# and a hammer alone collides with nothing in the family but reads as a generic
# tool rather than a forge. The anvil silhouette is unmistakable and shares no
# shape language with the other nine glyphs.
#
# Geometry: the body is a face slab (x=336..768, y=316..420), a waist
# (x=444..596, y=420..592) and a flared foot (x=304..716, y=592..708) — total
# ink 512x392 including the horn, inside SAFE_BOX once the renderer scales it.
#
# The horn is what makes this an anvil rather than an I-beam, so it is a
# separate wedge projecting left off the face, not a rounded corner on it: it
# leaves the slab at full 104px depth (x=336) and tapers to a 40px blunt tip
# at x=256, dropping the underside from y=420 to y=392 on the way. A sharp
# point would disappear at 48dp; 40px is above MIN_NEGATIVE_SPACE so it
# survives. The first two drafts folded the taper into the slab's left end and
# both read as a bump.
