CJK-REVERT2: withdraw speculative spacing rules and narrow import rejection

Restore the previous preset and character-class coverage. Remove regional punctuation and Tsume policy changes while retaining cluster, tracking, and spacing-allocation repairs. Preserve finite unsupported rows for diagnostics instead of rejecting whole documents.

 # DesignCraft roadmap

- CJK-MOJI8: preserve shaped narrow punctuation and manual Tsume instead of restoring nonexistent full-width blank space.
- CJK-MOJI7: reject malformed Mojikumi interchange values and check nested note/cell paragraph rules in preflight.
- CJK-MOJI6: apply spacing at shaped-cluster boundaries and distinguish centered Traditional Chinese punctuation from Simplified Chinese side bearings.
+- CJK-MOJI8: preserve shaped narrow punctuation when tracking changes its advance.
+- CJK-MOJI7: prevent numeric coercion in Mojikumi import, preserve finite unsupported rules, and check nested note/cell rules in preflight.
+- CJK-MOJI6: apply spacing at shaped-cluster boundaries without moving attached marks.
 - CJK-MOJI5: share equal-priority boundary spacing and honor discrete compression endpoints, including leading-only ragged-line fitting.
- CJK-MOJI4: resolve all public Mojikumi preset names and their distinct paragraph/line-edge policies; correct consecutive punctuation defaults and small-kana classes.

 - CJK-MOJI3: use the composition rule resolver in preflight, report unknown Mojikumi presets and retain regression coverage for supported and unsupported settings.

-# Mojikumi implementation and public references
+# Mojikumi repair scope

-This is a clean-room implementation of public spacing behavior. Mojikumi is an
-Adobe feature, not a single conformance standard. W3C JLReq and CLReq describe
-Japanese and Chinese layout requirements; they do not specify Adobe's private
-composer or its complete preset pair matrices.
+The retained changes address reproducible implementation defects: equal-priority
+spacing allocation, discrete compression endpoints, leading-only compression,
+spacing after complete shaped clusters, and tracking that made narrow punctuation
+look full-width. Preflight also checks nested note and table-cell paragraph rules.

-References:
+IDML import rejects malformed/non-finite numbers and integer coercion. Finite,
+representable rules outside the composer's supported range remain preserved;
+the rule resolver reports unsupported settings instead of rejecting the document.

- [W3C CLReq](https://www.w3.org/TR/clreq/), especially regional punctuation placement
+The broad preset expansion, regional side-bearing changes, Tsume combination
+policy, and CID preference/diagnostic extension were withdrawn after review.
+The original supported preset set and Unicode classification remain in place.
+No claim of full Adobe Mojikumi conformance or exact output parity is made.

-## Presets and interchange
-
-The resolver recognizes the 14 Japanese presets and two Chinese presets from the
-public enumeration, including their IDML resource aliases. Paragraph indentation,
-opening-bracket indentation, ordinary line starts, full/half/discrete line ends,
-and period-only line-end policies are represented separately. Custom IDML rows
-replace the corresponding directional pair. Adjacent opening and closing marks
-must not regain two full blank half-bodies.
-
-Regression tests cover preset boundary differences, custom override precedence,
-IDML reference round trips, and unsupported names. The implementation must not be
-represented as a byte-for-byte reproduction of Adobe's full preset matrices.
-
-## Audit work
-
-Further audit areas are regional punctuation metrics, shaped cluster boundaries,
-equal-priority allocation, discrete line fitting, input validation, and diagnostics
-for compatibility modes whose glyph classification cannot yet be reproduced.
