release: 2.2.0 — parameterized TOP / OFFSET / FETCH

CosmoSQLClient.CosmoKv 2.2.0 / CosmoSQLClient.CosmoKvHttp 2.2.0.

Implements task #35 from the v2.2 candidate list. The parser now admits
any scalar expression in paging slots, removing the integer-literal
restriction that blocked 8 stored procedures in CosmoMailServer's
Phase C migration plus the UPDATE TOP(n) claim-pending rewrites.

New surface:
  SELECT TOP @n           …               -- bare-form: atom only
  SELECT TOP (@A + @b)    …               -- paren-form: full expression
  SELECT … OFFSET @offset ROWS FETCH NEXT @limit ROWS ONLY
  UPDATE TOP(@Batch) … OUTPUT INSERTED.*
  DELETE TOP(@n)   … OUTPUT DELETED.*

Bare-form TOP keeps a tight grammar (ParseUnary only) to preserve the
`SELECT TOP 10 * FROM t` wildcard-vs-multiplication disambiguation.
Non-trivial paging expressions must be parenthesised (matches T-SQL
spec). OFFSET / FETCH and UPDATE/DELETE TOP(n) accept full expressions
since their syntactic position has no wildcard ambiguity.

Out of scope for v2.2 (deferred):
- Function-call DEFAULT in CREATE TABLE (task #34) — would require
  AST stringification or polymorphic JSON serialization to round-trip
  through the catalog. Phase B's workaround (drop DEFAULT, supply
  timestamps in C# call sites) is already in place and arguably
  cleaner. Revisit only if a new consumer needs it.

Tests: Phase9ParameterizedPagingTests adds 9 cases. Coverage includes
parameter-driven TOP/OFFSET/FETCH, arithmetic in TOP-parens,
UPDATE TOP(@Batch) for claim-pending, DELETE TOP(@n), negative-value
and string-value rejection, and the literal-TOP regression path.
Full suite stable: 240/240 across 3 consecutive runs.
