feat(resolvemcp): replace per-model tools with fixed meta tools, guarded filter writes and a function registry

Tools: list_tables, describe_table, select_table, insert_into_table, update_table,
delete_from_table, list_functions, call_function. Visibility follows the model rules.
Filter-based update/delete require filters (never dropped silently), cap the matched rows
(MaxWriteRows), support dry_run, and need a single-use confirm token bound to caller, table,
filters, data and the matched rows. RegisterFunction adds Go-callback and SQL-procedure
functions run in a transaction with BeforeCall/AfterCall hooks. Per-model tools and
resources are removed.

fix(pgsql): UPDATE with SET and a multi-placeholder WHERE renumbered the WHERE parameters
wrongly ($1, $2 became $3, $2); shift them in one pass.
