* fix(context): clarify get_node_property not-found contract (#877)
Add default= param to get_node_property and get_node_attributes so
callers can distinguish node-missing from property-missing using a
sentinel. Fix add_node_attribute calling mutation_callback outside
the lock. Tests added for all cases.
* fix(context): address Qodo review findings (#877)
* fix(context): wrap add_node_attribute mutation_callback in try/except (#877)
The PR claimed to move the callback back inside `with self._lock`, but
the diff only dropped a stray blank line -- the call stayed outside the
lock, unchanged. That's actually correct: self._lock is an RLock, and
_add_internal_node/_add_internal_edge deliberately release the lock
before invoking the callback too, so a slow/misbehaving callback never
holds up other threads. The real gap was that, unlike those two
siblings, this call site didn't catch exceptions from the callback.
Wrapped it the same way, with a regression test.

- validate_skos_hierarchy() re-walked every existing hierarchy edge in
the graph on each write, so one pre-existing cycle anywhere would
block all unrelated future SKOS writes. It now only traverses
concepts touched by the edges actually being written, while still
checking those against existing edges for cross-boundary cycles.
- In /api/ontology/load, `except HTTPException: raise` sat after a
broader `except Exception` clause that already matched HTTPException,
so a 422 raised after a successful OntologyIngestor parse was
silently swallowed and retried via the fallback RDF parser instead of
reaching the caller. Reordered the except clauses.
