Add shared hide_streamlit_chrome() helper that removes header bar,
hamburger menu, footer, and deploy button via CSS injection. Called
on every page. Add .streamlit/config.toml with minimal toolbar mode.

Convert single-page deduplicator into a multi-page suite. Home page shows
tool card grid. Deduplicator extracted to its own page (fully working).
8 stub pages added for Text Cleaner, Format Standardizer, Missing Values,
Column Mapper, Outlier Detector, Multi-File Merger, Validator & Reporter,
and Pipeline Runner — each with functional file upload and coming-soon UI.

Update README, CLI reference, and developer guide to cover delimiter

Auto-detects delimiter on upload and shows a selectbox with comma, tab,
semicolon, and pipe options. Changing re-reads the file immediately.
Line terminators (Windows/Unix/Mac) already handled by universal newlines.

Shows a read-only preview of the output rows below the editor,
updating as checkboxes and column dropdowns are changed.

Only the row chosen by the survivor rule (first, last, most-recent, etc.)
is checked by default. Other rows start unchecked.

Replace separate checkbox row and "Customize columns" toggle with a
unified st.data_editor grid — Keep checkboxes at the start of each row,
differing columns render as inline selectbox dropdowns.

Replace radio + Merge/Keep Both buttons with per-row checkboxes
and a single Confirm button. Users can now:
- Keep all rows (not duplicates) — check all, confirm
- Merge to one row — uncheck all but one, optionally customize columns
- Split a group — keep some rows, remove others (new capability)
Decision format changed from {action, survivor_idx, overrides} to
{keep_indices, overrides}. apply_review_decisions() updated to handle
all three modes. Batch actions updated accordingly.

Each match group card now has:
- Radio button to pick which row to keep as the base survivor
- "Customize columns" toggle showing only columns that differ
- Per-column selectbox to pick values from any row in the group
- Decisions stored as {action, survivor_idx, overrides} dicts
Added apply_review_decisions() that builds the final DataFrame by
applying survivor selection + column overrides without re-running
the dedup engine. Batch actions also use the new dict format.

Replace st.rerun() with on_click callbacks so decisions write to
session state before the natural rerun. Decided groups auto-collapse
with status in the label; undecided groups stay expanded. Added undo
button on decided groups.
