refactor: turn the repo into a two-plugin marketplace

tea and tdl were two repositories, each carrying its own
.claude-plugin/marketplace.json — two marketplaces to register for what
is one collection. Fold them into one.

The repo root is now the marketplace and nothing else: a single
.claude-plugin/marketplace.json whose entries point at ./plugins/tea and
./plugins/tdl. A plugin's root is its own directory under plugins/, so
${CLAUDE_PLUGIN_ROOT} still resolves inside it and every path a plugin
uses stays relative to itself — the hooks and the test roots needed no
adjustment beyond the move.

tea's files move with git mv, so its history and blame follow. tdl
arrives as a plain copy; its history stays in claude-skills/threedotslab.

test_payload_root asserted `tmp/` was ignored by REPO/.gitignore. The
rule is that tmp/ is ignored, not which file says so, and git reads every
.gitignore on the way up — so the test now walks up to the repo root the
same way git does.

+# Naming Rules
+
+## Strict Naming Convention Table
+
+| Pattern | Convention | Example |
+|---------|-----------|---------|
+| Entity constructor | `New{Type}(args...) (*Type, error)` | `NewTraining(...)`, `NewAvailableHour(...)` |
+| Panic constructor | `MustNew{Type}(args...) Type` | `MustNewFactory(...)`, `MustNewUser(...)` |
+| DB reconstruction | `Unmarshal{Type}FromDatabase(...)` | `UnmarshalHourFromDatabase(...)` |
+| Value from string | `New{Type}FromString(s string) (Type, error)` | `NewAvailabilityFromString(...)` |
+| Command struct | Imperative verb + noun (PascalCase) | `ScheduleTraining`, `CancelTraining`, `MakeHoursAvailable` |
+| Query struct | Noun phrase (PascalCase) | `AvailableHours`, `HourAvailability`, `AllTrainings` |
+| Handler type (exported) | `{ActionName}Handler` | `ScheduleTrainingHandler`, `CancelTrainingHandler` |
+| Handler struct (unexported) | `{actionName}Handler` | `scheduleTrainingHandler`, `cancelTrainingHandler` |
+| Handler constructor | `New{ActionName}Handler(...)` | `NewScheduleTrainingHandler(...)` |
+| Adapter type | Technology suffix | `FirestoreHourRepository`, `MySQLHourRepository`, `MemoryHourRepository` |
+| Adapter constructor | `New{Tech}{Entity}Repository(...)` | `NewFirestoreHourRepository(...)` |
+| DB model (SQL) | Tech prefix, unexported | `mysqlHour`, `postgresTraining` |
+| DB model (NoSQL) | `{Entity}Model` (exported for tags) | `TrainingModel`, `DateModel` |
+| Sentinel errors | `Err{Name}` | `ErrNotFullHour`, `ErrHourNotAvailable` |
+| Typed errors | `{Condition}Error` | `TooDistantDateError`, `NotFoundError` |
+| Zero check | `IsZero() bool` | `Availability.IsZero()`, `Factory.IsZero()` |
+| Application struct | `Application` in `app/` package | `app.Application` |
+| App sub-structs | `Commands`, `Queries` | `app.Commands`, `app.Queries` |
+| Composition root | `NewApplication(...)` in `service/` | `service.NewApplication(ctx)` |
+| gRPC client adapter | `{Service}Grpc` | `TrainerGrpc`, `UsersGrpc` |
+| Read model interface | `{Query}ReadModel` | `AvailableHoursReadModel` |
+
+## CRUD-to-Domain-Language Mapping
+
+CRUD terms are **forbidden** in domain code, commands, queries, and API endpoints. Use domain-specific language instead.
+
+| CRUD Term | Replacement Options | Example |
+|-----------|-------------------|---------|
+| Create | Schedule, Register, Place, Submit, Open, Enroll | `ScheduleTraining`, not `CreateTraining` |
+| Read | *(use noun phrase queries)* | `AvailableHours`, not `GetHours` |
+| Update | Approve, Reject, Reschedule, Move, Modify, Assign | `ApproveReschedule`, not `UpdateTraining` |
+| Delete | Cancel, Archive, Revoke, Close, Withdraw | `CancelTraining`, not `DeleteTraining` |
+| Get | *(avoid as prefix)* | `HourAvailability`, not `GetHourAvailability` |
+| Set | *(use specific verb)* | `MakeAvailable`, not `SetAvailability` |
+| List | *(use noun phrase)* | `AllTrainings`, not `ListTrainings` |
+| Fetch | *(avoid entirely)* | Use noun phrase queries |
+
+## Check Procedure
+
+1. Scan all type declarations and function names
+2. Flag any use of Create/Read/Update/Delete/Get/Set/List/Fetch in:
+   - Command struct names
+   - Query struct names
+   - Domain entity method names
+   - Handler type names
+3. Severity: CRITICAL for command/query names, WARNING for methods
