Replace the predicate unit test with an invariant on the real builder: a skill recorded
by a foreground create is in build_learning_graph() with zero uses, and an unmarked
never-used local skill is not. `hermes curator list-unmanaged` prints the actual
marker (created_by:learn) instead of hard-coding created_by:null. Docs: curator.md and
memory.md describe the learn marker and what the journey shows.
record_created now stamps created_by="learn" on foreground creates
(e.g. /learn) instead of leaving it unset, and the learning-graph filter
honors "learn" alongside "agent"/used. "learn" is a learning-signal
marker only: curator management stays keyed strictly on "agent"
(_is_curator_managed_record), so user-taught skills appear in /journey
without becoming eligible for autonomous curation.
Fixes#111317.

authored with AI assistance (Muse, Meta's Muse Spark) under the contributor's direction; the contributor reviewed the diff and ran the tests.
parse_frontmatter's malformed-YAML fallback stores every value as a string,
so a skill's `metadata` can be a str. `_category`/`_related` chained
`.get("metadata", {}).get("hermes", {})` and blew up with `'str' object has
no attribute 'get'`, taking down `build_learning_graph()` (and thus /journey
and `hermes journey`) whenever any installed skill had bad frontmatter.
Extract a `_hermes_meta()` helper that returns the nested dict only when it
really is one. Fixes the whole class, not just the two call sites.
Assemble a per-profile graph of memories and learned skills over time
(agent/learning_graph.py) and serve it at GET /api/learning/graph
(hermes_cli/web_server.py), with tests. The radial time axis the desktop
renders is derived from this payload; the REST path stays under /learning
for backend compatibility.
