Fixes the auditor's D118 withholds on main 497ad27 (record c1a92df) for sf.ddl.create-database.create-database-clone (quoted names, OR REPLACE) and sf.ddl.create-schema.create-schema-clone (OR REPLACE).

• CreateDatabase and CreateSchema gain or_replace, which is skipped when false so other trees are unchanged. OR REPLACE was parsed and then dropped.
• A Snowflake database name keeps its quoting (parse_quoting_identifier).
• tests/parser/test_snowflake_create_clone.rs pins the three trees.

The parser tests and the polyglot exact check pass. Gate: make check-merge RECORDER=0 is running on 0faa5be; the result will be posted here.

Gate (D94) on c793813, base main 77e10ee:

• CARGO_BUILD_JOBS=1 make check-merge RECORDER=0: exit 0 (syntax-coverage: 3475 forms checked, 0 problems).
• Coverage diff on catalogue c9ce0ff with evidence 6649fa9, main binary against head binary: forms +0/-0, obligations +0/-0, nothing lost.
• Receipt scan over every case, observe rows included: base accepted, head rejected: 0. Head accepted, base rejected: 7. Snowflake parsed 5 of those 7 (database-role-clone k2f294878f7ba 2003; create-stream-clone k6bedaffe7427, create-table-clone k78d7d9f59419 and iceberg-table-clone kdd9b422256c4, all 1422; create-database-role k9de9327a97ce accepted). The other 2 are unreceipted.
• This fixes the three fix(syntax): parse Snowflake CLONE kinds and security AS REPLICA forms #55 regressions recorded in audit 38bed22: CREATE DATABASE ROLE ;, CREATE DATABASE ROLE CLONE v1 ; and CREATE STREAM v1 CLONE v1 COPY = ( ) ;. Each has a regression case in test_snowflake_create_clone.rs.
• The database/schema clone withholds (OR REPLACE, quoted database names) are tree fixes. Their obligations were already satisfied, so the checker counts don't move; they clear when the auditor re-reads the trees.
