Add MakerNote numeric labels and docs

Bump VERSION to 0.4.39 and add extensive bounded numeric label support for MakerNotes. Adds many Canon CameraSettings/ShotInfo/main/MyColors label helpers and dispatches, expanded Fujifilm mk_fuji* decoded labels, and additional Panasonic main-table labels and mappings. Tightens ambiguous Ricoh/Minolta/Panasonic/Sony labels to avoid incorrect stable labels. Update CHANGES.md and interpretation_status docs to describe the new labels and revised priorities, and extend unit tests (exif_value_names_test.cc) to cover the new dispatches and mappings.

 # OpenMeta Changes
 
+## 0.4.39 - 2026-05-27
+
+Changes compared with `0.4.38`.
+
+### Added
+
+- Added bounded Canon MakerNote numeric labels for common CameraSettings,
+  ShotInfo, main, and MyColors scalar fields such as quality, drive, zoom,
+  contrast, saturation, focus range, image size, AE mode, white balance, slow
+  shutter, bracketing, control mode, ND filter, date stamp, and MyColors mode.
+- Added bounded Fujifilm MakerNote numeric labels for decoded real-file
+  `mk_fuji*` contexts, including sharpness, white balance, macro, slow sync,
+  auto bracketing, blur warning, color mode, and dynamic range fields.
+- Added bounded Panasonic MakerNote numeric labels for image quality, image
+  stabilization, audio, color effect, noise reduction, rotation, AF assist,
+  conversion lens, travel day, battery, text stamp, and related scalar fields.
+
+### Fixed
+
+- Fixed Fujifilm value-name dispatch for decoded `mk_fuji*` IFD tokens.
+- Stopped emitting ambiguous Ricoh `0x1003` and Minolta main `0x0103` labels
+  where the meaning depends on value type, model, or tag-name context that is
+  not available to the numeric value-name helper.
+- Tightened context-sensitive Panasonic contrast, Ricoh noise-reduction, and
+  Sony Tag2010B quality labels so ambiguous values remain unlabeled instead of
+  receiving a wrong stable label.

 | Exposure and gain | Standard EXIF exposure time, f-number, exposure program/mode, photographic sensitivity, exposure bias, exposure index, gain control, selected DNG baseline/raw-preview gain fields, matching XMP paths, and selected decoded vendor/MakerNote exposure names are queryable and promoted into cross-family exposure roles. Standard EXIF exposure program/mode and gain-control values plus selected Canon/Nikon/Sony/Fujifilm/Pentax/Olympus/Panasonic/Phase One/Kodak/Minolta/Sigma/Samsung/Ricoh MakerNote values carry human-readable labels where stable. Capture exposure facts are marked safe, while raw/DNG exposure adjustments are marked unsafe for rendered-image transfer. | Medium-high, about 91-94%. | More vendor MakerNote exposure print conversions and richer per-vendor exposure/gain labels. |
 | Color, white balance, profiles, and matrices | DNG color/calibration/reduction/forward matrix groups, white-balance vector groups, EXIF color-space evidence, ICC header/tag entries, XMP ICC/profile fields, PNG profile text carriers, RAW color/source-processing safety buckets, transfer hints, per-family grouped vendor color/WB candidates, long-tail camera-to-XYZ/RGB, style/color, and white-balance gain aliases, and cross-family concept candidates with full grouped value vectors are identified. ICC/profile and color-space records have a distinct `color_profile` semantic role, while camera RAW profile/look/tone-curve/style fields and vendor source color tables have a separate `source_color_transform` role marked unsafe for rendered-image transfer. Matrix/vector groups require numeric payloads with conservative minimum shapes before promotion. | Medium-high, about 85-92%. | Deeper camera/vendor color science interpretation is intentionally conservative, especially for rendered-image transfer. |
 | Lens correction and RAW processing | Lens-correction groups, black/white levels, linearization, CFA/sensor layout, raw-storage identifiers, vendor RAW/source-processing buckets, creative/picture style, film simulation, dynamic-range, optical correction, raw-development, computational, thermal, and stitch/panorama aliases, per-family vendor raw-storage/sensor/computational/thermal/stitch/source-processing table candidates, transfer hints, transfer diagnostics, and concept candidates with grouped table/vector values are classified for query and transfer safety. Lens-correction grouped tables require numeric payloads before promotion. | Medium-high, about 83-90%. | Long-tail per-model correction tables and richer numeric normalization. |
-| Vendor MakerNotes | Broad MakerNote naming and source-processing classification exists for common vendors and several live computational/thermal vendors. Unknown entries remain lossless and source-private subgroups distinguish preview, face geometry, computational, thermal, stitch/panorama, pixel-shift, multi-shot, composite, auto-lighting, RAW crop/active-area, source color-transform, source style/rendering aliases, lens-correction, raw-level processing data, and Phase One/Leaf RAW-processing fields handled by direct classification plus dedicated normalized helpers. Classified multi-field vendor groups now surface as grouped query/interpretation candidates where safe to expose structurally, and selected Canon/Nikon/Sony/Fujifilm/Pentax/Olympus/Panasonic/Phase One/Kodak/Minolta/Sigma/Samsung/Ricoh print conversions expose bounded human-readable labels for exposure-related UI. | Medium-high, about 88-93%. | ExifTool-style long-tail print conversions, encrypted/custom settings, and per-model private tables. |

 | Photoshop IRB | Raw resources are preserved and a bounded interpreted subset is decoded for fixed-layout resources, including Photoshop 2 info/color-table summaries, resolution/version/print data, print-flag bytes, border/background/effective-BW data, display info, grid/guide info, color sampler headers/records, descriptor-header summaries, path record summaries, alpha names/identifiers, captions, QuickMask info, URL/list data, autosave strings, `XMLData`, ImageReady XML text, thumbnail headers, channel options, clipping-path names, legacy halftone/transfer/duotone/EPS byte summaries, embedded ICC/XMP/EXIF resource byte counts, and embedded IPTC/XMP/ICC payload decode where enabled. | Medium, about 75-84%. | Broader resource-specific descriptor parsing and long-tail resource interpretation. |
