fix: resolve doctest failures, database bugs, and remove dead code

- Fix all 96 doctest failures across 20 files by adding hidden imports and
  proper test setup (68 pass, 33 intentionally ignored)
- Fix set_item_tags: wrap in transaction and replace item.id.unwrap() with
  proper error handling
- Fix get_items_matching: replace N+1 per-item meta queries with batch
  get_meta_for_items() call
- Fix get_item_matching: apply meta filtering instead of ignoring the parameter
- Remove duplicate doc comment in store_meta
- Remove dead code files: plugin.rs, plugins.rs, binary_detection.rs
  (never declared as modules)
- Apply cargo fmt formatting fixes
- Add keep.db to .gitignore

 **IMPORTANT:** Prefer to use the `write_file` tool if the edit is for the majority of a file, or if you are correcting previous problems made edits from other tools.
-
-## Tools
-
 **IMPORTANT**: Be very careful when quoting text in tool calls to add the right amount of escaping.
+**IMPORTANT:** When using `write_file`, you must provide the whole file, even the unchanged parts.
 
-### `write_file`
+**IMPORTANT:** `xxx | keep | zzz` must be as performant as possible in all situations.
-
-When editing files use the `write_file` tool to output the complete version of the corrected file.

+## Code Conventions
 
-## Code Style Guidelines
+- `anyhow::Result` for error handling; `thiserror` for custom error types (`src/services/error.rs`)
+- Plugin traits: `CompressionEngine`, `FilterPlugin`, `MetaPlugin`
+- Dynamic trait objects use `clone_box()` for `Clone` on `Box<dyn Trait>`
+- Plugin registration uses `ctor` constructors at module load time
+- Filter plugins must implement `filter()`, `clone_box()`, and `options()`
+- Meta plugins extend `BaseMetaPlugin` for boilerplate reduction
+- Enum string representations: `#[strum(serialize_all = "snake_case")]`
+- Lint rules: `deny(clippy::all)`, `deny(unsafe_code)` (except `libc::umask` in main.rs)
+- Feature flags: `default = ["magic", "lz4", "gzip"]`; optional: `server`, `mcp`, `swagger`
 
-### Imports
+## Testing
-- Group imports in order: standard library, external crates, local modules
-- Use explicit imports over glob imports (`use std::fs::File;` not `use std::fs::*;`)
 
-### Documentation
+- Tests in `src/tests/` mirroring `src/` structure; shared helpers in `src/tests/common/test_helpers.rs`
-- Document all public APIs with rustdoc
+- Key helpers: `create_temp_dir()`, `create_temp_db()`, `test_compression_engine()`
-- Use examples in documentation only when helpful
+- Test naming: `test_<feature>_<scenario>`
 
 ## Procedures
 
 ### Fix build problems
 
-1. Check the project: `TERM=dumb cargo check`.
+1. `TERM=dumb cargo check`
-2. If there are errors or warnings, create a new sub agent (expert rust developer) that uses the `TERM=dumb cargo check` output as input, planned using strategic thinking.
+2. Read affected files, fix errors, preserve functionality, don't downgrade versions
-   a. Read all affected files
+3. Prefer `write_file` for full file rewrites; repeat from step 1
-   d. Plan the fixes using strategic thinking:
-      - Read other files if they provide context or examples
-      - Look up relevant API information
-      - Do not downgrade versions
-      - Preserve functionality
-      - Use `TERM=dumb cargo fix` if appropriate.
-      - Prefer the `write_file` tool if there is evidence of double escaping
-      - You must generate the full file contents when using `write_file` or it will be truncated.
-   c. Return the list of files modified
-3. If any files were modified, loop back to 1.
 
 ### Fix formatting
 
-1. Format the project the project: `TERM=dumb cargo fmt`
+1. `TERM=dumb cargo fmt`
-2. Continue with the fix build problems procedure.
