Subject: [PATCH 3/6] feat(localize): extract file_type from filename prefix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add `extract_file_type_from_file_name` to parse prefixes like `_daily`
from filenames (e.g. `20260412-123456_daily.md` → `"daily"`).

Insert the result into `initial_location` in `localize_stream_file` so
all localized shards carry a `file_type` dimension value.

Also register the `file_type` dimension in `TaskConfiguration` so the
propagation contract is documented.

Subject: [PATCH 4/6] feat: add `streamd daily` command

`streamd daily [YYYYMMDD]` opens the earliest existing daily file
(file_type=daily) whose timestamp falls within the target date.
If no such file exists it creates `<timestamp>_daily.md` and opens it.
Date defaults to today in the repository timezone.

+### R21a: Daily Command Behavior
+
+`streamd daily [YYYYMMDD]` provides quick access to the daily journal entry for a given date.
+
+**Date resolution:**
+- If a `YYYYMMDD` argument is provided, it is parsed as the target date.
+- If no argument is given, today's date is used, interpreted in the repository timezone (from `.streamd.toml`, defaulting to UTC).
+
+**File lookup:**
+- All markdown files in the base folder are localized.
+- Files with `file_type = "daily"` whose root shard `moment` falls within the target date (in the configured timezone) are collected.
+- The file with the earliest `moment` is opened in `$EDITOR` (defaults to `vi`).
+
+**File creation:**
+- If no matching file is found, a new file is created at `<now_local>_daily.md` (e.g. `20260413-083000_daily.md`) containing `# ` and opened in the editor.
+- The `_daily` suffix is permanent — it identifies the file type and is not renamed after editing.
