harden: deep-freeze PROGRAM_IDS, STAKE_PROGRAM_IDS, and STAKE_IX

[0x-SquidSol]

Summary

• as const is compile-time only — it does NOT prevent runtime mutation
• Without Object.freeze, a supply-chain attack or prototype pollution could silently redirect program IDs:

  (PROGRAM_IDS as any).mainnet.percolator = "attacker-program";

• This would redirect all user transactions to an attacker-controlled program
• Fix: Deep-freeze PROGRAM_IDS (both nested network objects + top-level), STAKE_PROGRAM_IDS, and STAKE_IX
• Follows the precedent of IX_TAG which was frozen in PR fix(abi): remove redundant IX_TAG mutations, freeze object #135
• Zero code paths mutate these objects — all accesses are read-only

Objects frozen:

Object	File	Freeze Type	Threat
PROGRAM_IDS	program-ids.ts	Deep (inner + outer)	Program ID substitution
STAKE_PROGRAM_IDS	stake.ts	Shallow (flat strings)	Staking redirect
STAKE_IX	stake.ts	Shallow (flat numbers)	Instruction tag corruption

Test plan

• No new test failures (729 passed, same 16 pre-existing)
• Verified: no code path mutates these objects
• Env var overrides (PROGRAM_ID, STAKE_PROGRAM_ID) still work — they return early before touching frozen objects
