Fix for issue #1791: by pretty printing mangled platform_map codeblock in seed-canonical-heads.mjs

[drQedwards]

Mangled platform_map code block now looks readable with its canonical constants to align and look like the constants for the canonical_head_group code block.

this closes and resolves issue #1791 only after this PR gets merged.

Only then can we begin fixing the issues we the mismatch errors in CAIP-2 in the metadata and labels directory when it comes to bip122, aka bitcoin having a mismatch where it is labeled in the metadata directory coherently, but not coded in the labels.

Note

Medium Risk
TypeScript syntax (as const, type annotations) in a .mjs file may break running the seed script with plain Node unless another runner is used; platform lookup behavior is equivalent for existing entries but warns on misses.

Overview
Reformats PLATFORM_MAP in scripts/seed-canonical-heads.mjs from a compact object keyed by CoinGecko platform names to an explicit array of { platform, caip2, assetNamespace } entries, styled like CANONICAL_HEAD_GROUPS.

platformToCaip19 is moved above the canonical-head constants and now resolves platforms via PLATFORM_MAP.find() instead of bracket lookup; unknown platforms still return null but also console.warn. The same chain/namespace values are preserved.

The diff also adds TypeScript-style annotations (as const, parameter/return types, typed summary array) and minor formatting tweaks in seed(); there is no change to canonical-head groups or label read/write logic.

B

See? The bug is resolved. As I mentioned, issue #1792 only gets resolved and closed after merging this PR .

Only then can the bigger issue of the mismatch error in the metadata and labeling directories for bip122 Bitcoin can be fixed and addressed.

It is Bip122 not bip110 🙄
