1.0.4 - Full Editability & Negative-Value Parser Fix
* CATG Editor: every node and reach column is now editable
(coordinates, scale, area, dci, ici, name, reach length/slope,
n_coords, flags) — not just print flags
* CATG Editor: fixed parser bug where reaches with negative slopes (or
other negative numeric fields) were silently dropped. Numeric regex
groups now accept negative values, and the parser advances a fixed 3
lines per reach so coord lines are preserved even on unparseable
headers
* CATG Editor: writer now uses a generic field-splicer that preserves
RORB's fixed-column format on save — original decimal counts are
mirrored (e.g. user-entered 1.9 is written as 1.900 when the original
had 3 decimals), and column widths are anchored. Numeric fields are
right-aligned (eats leading whitespace on growth); name fields are
left-aligned (eats trailing whitespace on growth)
* CATG Editor: per-field change tracking via _original_* snapshots;
unsaved-changes detection covers every editable attribute
* CATG Editor: invalid cell input (wrong type, out-of-range flags)
reverts to the previous value

1.0.3 - Compatibility & Sync
* QGIS 4.0 / Qt6 compatibility: migrated remaining short-form Qt enums
(Qt.RichText, Qt.UserRole) to fully-qualified names
(Qt.TextFormat.RichText, Qt.ItemDataRole.UserRole)
* Declared supportsQt6=True and qgisMaximumVersion=4.99
* CATG Editor: synced fully with the standalone script (parser,
writer, batch print-flag operations, filter bar, unsaved-changes
tracking, file summary)

1.0.2 - Improvement
* CATG Editor: Extract full table of the catg text file in a table
format

1.0.1 - Bug Fix
* CATG Editor: Fixed critical PrintFlag parsing bug in REACHES and
NODES section and added proper column ordering matching RORB file
format.

1.0.0 - Initial release
* CATG Editor: interactive table view of RORB catchment files
* CATG Editor: editable print flags for nodes and reaches
* CATG Editor: batch operations, filter, clipboard support
* STM Editor: open existing or create new non-uniform STM files
* STM Editor: guided New STM wizard with full section scaffolding
* STM Editor: add/delete bursts, pluviographs, hydrograph stations
* STM Editor: delimiter-preserving (tab/comma) round-trip editing
* Both: structured table editing — no manual text-file formatting
* Both: tree navigation, colour-coded sections, help panel
* Both: lossless file reconstruction on save
