perf(shared-icons): mark package as side-effect-free for tree-shaking

Browse source 
phosphor-svelte ships a 28 MB lib of per-icon Svelte components and
does not declare "sideEffects" in its own package.json. When
@mana/shared-icons re-exports that package without its own
"sideEffects" hint, Vite/Rollup conservatively assume every
transitive module evaluation might matter and cannot aggressively
prune unused icons across chunk boundaries.

Our re-exports (index.ts: `export * from 'phosphor-svelte'` + a small
name→component registry) are pure ESM barrels with no top-level
runtime code, so flagging the package as side-effect-free is safe
and lets the bundler drop unused icons and skip evaluating the
icon-registry module from chunks that only want a named icon.
