…ified table
Snowflake (verified against the live service) decodes octal \o..\ooo
(greedy, 1-3 digits), hex \xhh and unicode \u+4-hex escapes (malformed
ones are compilation errors), and the C-style \b \f \n \r \t; \' \"
\\ escape themselves; any other escaped character keeps the character
and drops the backslash ('\a' = 'a', '\Z' = 'Z' — NOT the MySQL BEL/^Z
mappings the shared table applied before).
Gated behind a new dialect hook supports_snowflake_string_literal_escapes
(default false) so no other dialect changes behavior.

The 1.86.0 pin broke on dependency resolution unrelated to any code change: sqlparser's recursive-protection feature pulls recursive -> stacker -> psm, and the freshly released psm 0.1.31 adds a build-dependency on ar_archive_writer 0.5.2, which requires rustc 1.88. Neither crate commits a lockfile, so the lint jobs resolve latest versions and benchmark-lint failed at resolution. Both clippy jobs verified clean locally on 1.89.0.
