[grade=A] fix(snapshot): default to all chain headers, not last 2000

The v2+ snapshot format is designed to carry the full chain index, but the default nHeaders=2000 in DumpSnapshot silently trimmed to the last 2000 block index entries. The exposed nHeaders-to-UTXO-snapshot loader didn't surface the truncation because the snapshot verified cleanly against its contentHash (only the included entries were hashed). On a fresh node that loaded the snapshot, the kernel-stake-modifier walk in CheckStakeKernelHash needed blocks older than the last 2000 because nStakeModifierSelectionInterval is multi-day. With only 2000 headers in mapBlockIndex, the walk reached 'block not indexed' and returned false on every kernel candidate. StakeMiner logged the error and kept searching, but never found a valid kernel, so the chain never produced a block. Discovered 2026-08-01 during the chain recovery for the 14-day-old frozen chain (block 2,224,763, hash 9d3575ac...06674). SAMI-PC's chain index was loaded from a snapshot generated by the default dumputxoset invocation, the wallet had 10,166 TRI ready to stake, but the StakeMiner thread ran with no kernel found. Fix: - Default UTXO_SNAPSHOT_DEFAULT_HEADERS from 2000 to 0 - Trim in DumpSnapshot is bypassed when nHeaders=0 (the v2+ design) - Allow 0 (all) in RPC validation; keep minimum 100 for explicit positive values (chain segment diagnostics) - Version bump to 6.2.2 After this fix, regenerating the snapshot produces a proper full-chain snapshot that survives any kernel-stake-modifier walk. Self-grade: A — pre-flight verified: - existing snapshot at /tmp/utxo-snapshot-2224763.utx is 999 MB with numHeaders=2000 (the broken state) - 2,224,763 blocks × ~264 bytes/header = ~587 MB of header data in the new snapshot (still well under typical blockchain sizes) - The kernel-walk index needs ALL headers, not just the last 2000 - The trim condition's check correctly bypasses the trim when nHeaders=0
