Existing users who only ever launch Hermes (never re-run an installer)
kept their managed Node 22 tree forever: the heal path only fired for
*broken* trees, and a healthy 22 passes the --version probe. Now
"outdated" heals the same way "broken" does, on both sides of the mirror:
- hermes_constants.py: find_hermes_node_executable() checks
_managed_node_tree_outdated() (managed node major <
_HERMES_NODE_TARGET_MAJOR) and routes through the existing
once-per-process heal_hermes_managed_node(), which redownloads
latest-v26.x. When the heal fails (offline, download error) the
outdated-but-runnable tree is still returned — old Node beats no Node.
- scripts/lib/node-bootstrap.sh: _nb_managed_node_needs_heal() gains the
matching _nb_managed_node_outdated() rung, so heal_managed_node agrees
with the Python side.
This is the same shape as the managed-uv flow: resolve the managed
runtime, notice it can't satisfy the requirement, provision the right one
in place, fall back gracefully.
Tests (tests/test_hermes_constants.py): outdated tree triggers heal and
returns the upgraded binary; failed heal still serves the old tree; an
at-target tree never heals (heal stub raises).
