fix(routing): register the 5 unregistered skills and split the buy-intent route

The routing table listed only 7 of the repo's 12 skills. gmgn-contract-dd,
gmgn-cooking, gmgn-holder-analysis, gmgn-wallet-analysis and gmgn-token-buy
were absent, so an unregistered skill effectively did not exist to the router.

Three routes also sent buy-side asks somewhere that cannot answer them:

  - "is this token safe" / "check this token" went to gmgn-token, which
    returns raw fields and no verdict. Split into three rows: a token name or
    symbol with buy intent goes to gmgn-token-buy (the only skill that
    resolves a name to the one right contract and sizes the order); a bare
    address wanting a score goes to gmgn-contract-dd; raw fields for an
    address already in hand stay with gmgn-token.
  - "buy TOKEN" went straight to gmgn-swap, bypassing due diligence. Narrowed
    to the skip-the-checks case; a plain "buy TOKEN" is gmgn-token-buy.

Measured on a 20-case routing eval (10 positives) with `claude -p`, first
Skill call recorded, 12 skills installed:

  routing table unchanged            recall 1/10 and 3/10 over two runs
  routing table with this change     recall 7/10, reproduced exactly twice

Precision stayed 100% with zero false positives in every run. The 3 remaining
misses are eval cases with no token name, a placeholder address, and an
unsupported chain — none of them resolvable by routing.

Description-level fixes were tried first and measured dead: narrowing
gmgn-token's description, adding a runtime hand-off to gmgn-token's body, and
rewriting gmgn-token-buy's own description each scored 0/10.
