Fixes #2568
## Problem
`age_split()` passes the delimiter verbatim to PostgreSQL's
`regexp_split_to_array()`, which compiles it as a regular expression. This
causes:
- `split('a.b.c', '.')` → `["", "", "", "", "", ""]` (dot matches every char)
- `split('a+b+c', '+')` → ERROR (invalid regex quantifier)
- `split('a|b', '|')` → `["a", "|", "b"]` (alternation splits at every
position)
Meanwhile, `age_replace()` treats the same delimiter literally, making the
two functions internally inconsistent.
openCypher defines the split delimiter as a **literal string**, matching
Neo4j, Memgraph, and FalkorDB behavior.
## Fix
Replace `regexp_split_to_array` with `string_to_array` in `age_split()`.
PostgreSQL's `string_to_array` treats the delimiter as a plain literal string,
which is the correct openCypher semantics.
## Test
Added regression tests for regex metacharacter delimiters: `. `, `|`, `+`,
and multi-dot `a.b.c.d`.
