refactor: memo filter 

- Updated memo and reaction filtering logic to use a unified engine for compiling filter expressions into SQL statements.
- Removed redundant filter parsing and conversion code from ListMemoRelations, ListReactions, and ListAttachments methods.
- Introduced IDList and UIDList fields in FindMemo and FindReaction structs to support filtering by multiple IDs.
- Removed old filter test files for reactions and attachments, as the filtering logic has been centralized.
- Updated tests for memo filtering to reflect the new SQL statement compilation approach.
- Ensured that unsupported user filters return an error in ListUsers method.

# Maintaining the Memo Filter Engine
The engine is memo-specific; any future field or behavior changes must stay
consistent with the memo schema and store implementations. Use this guide when
extending or debugging the package.
## Adding a New Memo Field
1. **Update the schema**
- Add the field entry in `schema.go`.
- Define the backing column (`Column`), JSON path (if applicable), type, and
allowed operators.
- Include the CEL variable in `EnvOptions`.
2. **Adjust parser or renderer (if needed)**
- For non-scalar fields (JSON booleans, lists), add handling in
`parser.go` or extend the renderer helpers.
- Keep validation in the parser (e.g., reject unsupported operators).
3. **Write a golden test**
- Extend the dialect-specific memo filter tests under
`store/db/{sqlite,mysql,postgres}/memo_filter_test.go` with a case that
exercises the new field.
4. **Run `go test ./...`** to ensure the SQL output matches expectations across
all dialects.
## Supporting Dialect Nuances
- Centralize differences inside `render.go`. If a new dialect-specific behavior
emerges (e.g., JSON operators), add the logic there rather than leaking it
into store code.
- Use the renderer helpers (`jsonExtractExpr`, `jsonArrayExpr`, etc.) rather than
sprinkling ad-hoc SQL strings.
- When placeholders change, adjust `addArg` so that argument numbering stays in
sync with store queries.
## Debugging Tips
- **Parser errors** – Most originate in `buildCondition` or schema validation.
Enable logging around `parser.go` when diagnosing unknown identifier/operator
messages.
- **Renderer output** – Temporary printf/log statements in `renderCondition` help
identify which IR node produced unexpected SQL.
- **Store integration** – Ensure drivers call `filter.DefaultEngine()` exactly once
per process; the singleton caches the parsed CEL environment.
## Testing Checklist
- `go test ./store/...` ensures all dialect tests consume the engine correctly.
- Add targeted unit tests whenever new IR nodes or renderer paths are introduced.
- When changing boolean or JSON handling, verify all three dialect test suites
(SQLite, MySQL, Postgres) to avoid regression.

# Memo Filter Engine
This package houses the memo-only filter engine that turns CEL expressions into
SQL fragments. The engine follows a three phase pipeline inspired by systems
such as Calcite or Prisma:
1. **Parsing** – CEL expressions are parsed with `cel-go` and validated against
the memo-specific environment declared in `schema.go`. Only fields that
exist in the schema can surface in the filter.
2. **Normalization** – the raw CEL AST is converted into an intermediate
representation (IR) defined in `ir.go`. The IR is a dialect-agnostic tree of
conditions (logical operators, comparisons, list membership, etc.). This
step enforces schema rules (e.g. operator compatibility, type checks).
3. **Rendering** – the renderer in `render.go` walks the IR and produces a SQL
fragment plus placeholder arguments tailored to a target dialect
(`sqlite`, `mysql`, or `postgres`). Dialect differences such as JSON access,
boolean semantics, placeholders, and `LIKE` vs `ILIKE` are encapsulated in
renderer helpers.
The entry point is `filter.DefaultEngine()` from `engine.go`. It lazily constructs
an `Engine` configured with the memo schema and exposes:
```go
engine, _ := filter.DefaultEngine()
stmt, _ := engine.CompileToStatement(ctx, `has_task_list && visibility == "PUBLIC"`, filter.RenderOptions{
Dialect: filter.DialectPostgres,
})
// stmt.SQL -> "((memo.payload->'property'->>'hasTaskList')::boolean IS TRUE AND memo.visibility = $1)"
// stmt.Args -> ["PUBLIC"]
```
## Core Files
| File | Responsibility |
| ------------- | ------------------------------------------------------------------------------- |
| `schema.go` | Declares memo fields, their types, backing columns, CEL environment options |
| `ir.go` | IR node definitions used across the pipeline |
| `parser.go` | Converts CEL `Expr` into IR while applying schema validation |
| `render.go` | Translates IR into SQL, handling dialect-specific behavior |
| `engine.go` | Glue between the phases; exposes `Compile`, `CompileToStatement`, and `DefaultEngine` |
| `helpers.go` | Convenience helpers for store integration (appending conditions) |
## SQL Generation Notes
- **Placeholders** — `?` is used for SQLite/MySQL, `$n` for Postgres. The renderer
tracks offsets to compose queries with pre-existing arguments.
- **JSON Fields** — Memo metadata lives in `memo.payload`. The renderer handles
`JSON_EXTRACT`/`json_extract`/`->`/`->>` variations and boolean coercion.
- **Tag Operations** — `tag in [...]` and `"tag" in tags` become JSON array
predicates. SQLite uses `LIKE` patterns, MySQL uses `JSON_CONTAINS`, and
Postgres uses `@>`.
- **Boolean Flags** — Fields such as `has_task_list` render as `IS TRUE` equality
checks, or comparisons against `CAST('true' AS JSON)` depending on the dialect.
## Typical Integration
1. Fetch the engine with `filter.DefaultEngine()`.
2. Call `CompileToStatement` using the appropriate dialect enum.
3. Append the emitted SQL fragment/args to the existing `WHERE` clause.
4. Execute the resulting query through the store driver.
The `helpers.AppendConditions` helper encapsulates steps 2–3 when a driver needs
to process an array of filters.
