refactor(content,core,app,editor,learn): Learn's content in pure Dart, for its agent
ADR 0044's D49 (amended in building it): what reads and seals Learn's
content moves out of the Flutter packages, so Learn's agent, which runs
without Flutter, shares it rather than repeating the privacy rules.
packages/halkyon_content (new, pure Dart) takes from halkyon_app the
envelope and its cipher, SealedFile, UnlockedAccountKeys, shared
spaces' gateway with SharedKeys and KeyPins, FileCache and
FileServerGateway, with their fakes and tests; halkyon_app exports it,
so no app changes. Its rich_text.dart takes RichContent from
halkyon_editor, which exports it. newAccountKeys makes an agent's key
pair. halkyon_core takes DelayedDeletions and gains SyncRequests, what a
synced gateway asks of the sync, which SyncService implements.
apps/learn/halkyon_learn_core (new, pure Dart) takes Learn's privacy,
sync, payloads and the models, codecs, gateways and repositories of
studysets, cards, notes, tags and feedback, with what they reach of
files, learning paths, citations and study options; the app imports them
from there. A subject's icon, colour and name stay in the app
(SubjectLook); what only the app shows (progress, exam coverage, the
card browser, deletions' waits) stays too. Nothing changes for people
using the apps.

Halkyon Learn's content in pure Dart (Halkyon's ADR 0044, D49): what the app and Learn's agent

both read and write, so the privacy rules and the payloads live in one place.

- `core/`: the payloads' envelope and codecs (`content/`), privacy (`privacy/`: `Privacy`,

`ContentKeys`, the ledger, shared spaces' keys), the sync's spaces (`sync/`: `SpaceRouter`,

`SyncSpaceLookup`, positions), people's files (`asset/`), `LatestValue` and `watchReads`

feat(learn): Learn's agent, an MCP server suggesting in shared studysets
Halkyon's ADR 0044, step 6c (D7, D49 to D52). apps/learn/halkyon_learn_agent
is one executable, `halkyon-agent --instance URL sign-in | sync | mcp`:
- sign-in keeps the token read from stdin, signs in with it, makes the
agent's key pair on its first sign-in, keeps it before setting the
public halves on the register (agents.setKeys), and syncs;
- it opens its data as the app's _openPersonData does, on
halkyon_learn_core and halkyon_content: its own SQLite database, the
sync's space router, its keys and those of the spaces shared with it,
and the repositories of studysets, cards, notes, paths, files and
feedback;
- mcp serves ten tools over stdio (dart_mcp): list, read and search the
studysets shared with it, suggest a change or a new card or note,
report, list a studyset's suggestions and reply. Each syncs first and
a suggestion again at once; a refusal is the tool's error;
- its files live in $XDG_CONFIG_HOME/halkyon-agent/<host>, 0700 and
0600, refused when others may read them (D50);
- tool/install.sh builds it with `dart build cli` (libsodium and SQLite
bundled) and copies it to its user on the host, the build before kept
(D52).
The synced gateways of learning paths and files, and the fakes of the
core's gateways, move into halkyon_learn_core (its testing.dart), which
the app's tests and the agent's share.
