Release v4.0.3 - Retire Stoic Awakening at height 150000

Mandatory update before block height 150000.

Live mainnet data showed the Stoic Awakening min-difficulty escape
(active since genesis, MinDifficultyActivationHeight = 1) firing far
more often than assumed under perfectly stable hashrate: block
discovery is a Poisson process, so a >120s gap occurs ~13.5% of the
time by pure statistical variance (e^-2), not the ~5% the original
design assumed. Worse, when an escape block lands on the last block of
a 2016-block retarget period, CalculateNextWorkRequired() inherits its
crashed nBits as the baseline for the entire next epoch, requiring
several +300%-capped periods (days) to recover - during which the
chain is trivially attackable and mines far more than the intended
1,440 blocks/day. A live diagnostic mid-cascade (tip 82858) showed the
recovery self-prolonging as opportunistic miners piled onto the cheap
difficulty window, keeping realized block times (1.48s avg) below
target even after a x4 difficulty jump.

New consensus parameter Consensus::Params::StoicAwakeningEndHeight
(-1 = never, the default for every network except mainnet) height-gates
the end of the escape in GetNextWorkRequired() and
PermittedDifficultyTransition() (src/pow.cpp), alongside the existing
fPowAllowMinDifficultyBlocks/MinDifficultyActivationHeight checks.
Mainnet sets it to 150000 (src/kernel/chainparams.cpp), chosen with
~4-5 weeks of real lead time from the tip at decision time. Blocks
below 150000 keep validating exactly as before - this is forward-only,
not retroactive. Testnet/testnet4/regtest are unaffected.

If you update before reaching height 150000, you won't notice the
switch at all: nBits simply stops changing mid-period from that height
onward, exactly like Bitcoin mainnet.

Elektron Net StartOS Release v4.0.2

Release v4.0.2 - MuHash UTXO Attestation Mainnet Activation

Mandatory update before block height 137000.

Starting at block height 137000, the network switches to a more
efficient UTXO attestation method (incremental MuHash accumulator
instead of a full rescan at every checkpoint). Nodes running older
software will validate the attestation incorrectly from that height
onward and fall off the main network.

If you update before reaching that height, you won't notice the
switch at all. If you miss it: your node automatically detects that
its own chain has fallen behind and resyncs itself via a checkpoint
snapshot once the current software is running — nothing is lost,
just unnecessary downtime.
