Hindsight now ships from its maintainer's repo (vectorize-io/hindsight,
hindsight-integrations/hermes) through plugin-catalog/hindsight.yaml, so the
in-tree copy under plugins/memory/hindsight goes away. Homes that still name
`memory.provider: hindsight` are migrated by hermes_cli/memory_provider_migration.py
(the `hermes update` hook and the first agent start install the catalog plugin);
that path is untouched here.
Core-side special cases that only made sense with the bundled copy go with it:
the `memory.hindsight` LAZY_DEPS feature, `_provider_pip_dependencies`'s
`hindsight-all` expansion in `hermes memory setup` (the plugin's own
`_ensure_local_runtime()` installs the embedded runtime now), the compat-manifest
pointers of the deleted module, and prose that listed hindsight among the in-tree
providers. Generic provider-name lists, the HINDSIGHT_* env hints and the API-key
redaction pattern stay — a catalog-installed hindsight still uses them.
Revert this commit alone to restore the bundled provider.
