fix(es/parser): cover type-signature TS2371 without duplicates
Drop eager InDeclare emits that double-fired with the post-list walker
for declare functions. Recover AssignPat in signature bindings as
TS2371 and walk nested object/array defaults in type/call/method
signatures.

fix(es/parser): honor no_early_errors and recheck TSX arrows
emit_strict_mode_err must respect TsSyntax::no_early_errors like
emit_err. Outer TSX try_parse_ts also sets IgnoreError, so re-run
validate_arrow_params after that speculative parse commits.

fix(es/parser): do not emit TS2371 for declare const defaults
Object shorthand defaults under InDeclare also appear in ambient
variable bindings such as `declare const { a = 1 }`, which TypeScript
accepts. Drop the eager object-pattern check and limit binding-element
TS2371 to parameter lists; declare signatures still use the post-parse
walk.

fix(es/parser): scan non-ASCII RegExp flags as IdentifierPart
cur() only yields the first UTF-8 byte, so flags starting with a
non-ASCII IdentifierPart (e.g. /a/π\u0067) were skipped. Use
cur_as_char() and is_ident_part() before deciding there are no flags.

fix(es/parser): cover remaining UniqueFormalParameters paths
Apply uniqueness checks after speculative TS arrow parses leave
IgnoreError, buffer simple-list duplicates for auto-detected modules,
and cover conditional typed / generic async arrow parsers.

fix(es/parser): reject unicode escapes in RegExp flags
ECMA-262 makes a Syntax Error when RegExp flags contain a Unicode
escape sequence. The lexer already detected escapes via
read_word_as_str_with but discarded has_escape; honor that flag and
also accept flags that begin with a backslash escape.
