Subject: [PATCH 1/4] refactor(slasher): rename ATTESTED_DESCENDANT_OF_INVALID
 -> PROPOSED_DESCENDANT_OF_INVALID

Rename the slashing offence and its associated config knob, env var, helm
value, and terraform variable to reflect that the slash now targets the
proposer that publishes a descendant checkpoint to L1, not its attestors.

Breaking for operators: SLASH_ATTEST_DESCENDANT_OF_INVALID_PENALTY ->
SLASH_PROPOSE_DESCENDANT_OF_INVALID_PENALTY (see v5.0.0 changelog).

+## Overview
+
+**Migration difficulty**: TODO
+
+## Breaking changes
+
+### `SLASH_ATTEST_DESCENDANT_OF_INVALID_PENALTY` renamed to `SLASH_PROPOSE_DESCENDANT_OF_INVALID_PENALTY`
+
+The slashing offence for building on an invalid checkpoint has been renamed to reflect that the slash targets the proposer of the descendant checkpoint published to L1, not its attestors.
+
+**v4.x:**
+
+```bash
+SLASH_ATTEST_DESCENDANT_OF_INVALID_PENALTY=<value>
+```
+
+**v5.0.0:**
+
+```bash
+SLASH_PROPOSE_DESCENDANT_OF_INVALID_PENALTY=<value>
+```
+
+**Migration**: rename the variable in your node environment, systemd units, helm values, or any deployment scripts. The underlying offence enum (`OffenseType`) has also been renamed from `ATTESTED_DESCENDANT_OF_INVALID` to `PROPOSED_DESCENDANT_OF_INVALID`, which only affects downstream tools that parse offence types from the slasher.

+## New features

+## Changed defaults

Subject: [PATCH 4/4] refactor(slasher): use longer-form name
 PROPOSED_DESCENDANT_OF_CHECKPOINT_WITH_INVALID_ATTESTATIONS

Rename the offence (and its config knob, env var, helm value, terraform
variable, etc.) from the previous shorter PROPOSED_DESCENDANT_OF_INVALID
form to spell out the exact condition: a descendant of a checkpoint that
had invalid (or insufficient) attestations.
