v0.6.0

Added

• Add attributable compiler, hydration, execution-cleanup, observer, and
  result-memory benchmarks with dimensional and component controls, fresh-worker
  transient-allocation/RSS samples, and live buffered/unbuffered engine and
  proxy comparisons.
• Add a deterministic release-consistency check for active plans, support and
  security policies, benchmark baseline labels, maintained commands, and
  configuration paths.
• Add a data-driven connection state-transition matrix covering clean, active
  cursor, transaction, quarantine, and closed lifecycle paths.
• Add an automated clean no-dev consumer lifecycle test suite covering
  connection, compilation, read/write/aggregate terminals, streaming cursors,
  savepoint transactions, and safe failure diagnostics.
• Add a concise terminal choice decision matrix and driver caveats to the results
  and writes guide.
• Add an exception troubleshooting matrix mapping all error classes to safe
  application remediation actions and redaction guarantees in the public API
  reference.
• Add guidance on engine parameter limits, packet ceilings, buffered versus
  unbuffered cursor streaming, and deterministic pagination ordering.

Changed

• Compare benchmark candidates with immutable v0.5.0 in both source orders
  using generic artifacts and repeated identical-source noise controls, so
  sub-millisecond percentages and within-control variance are not actionable.
• Reduce transient allocation for high-cardinality IN and batch-insert
  compilation by removing placeholder, row-group, and validated-binding list
  intermediates while preserving SQL and binding contracts.
• Reduce associative hydration's per-row validation allocation by iterating
  fetched keys in place while preserving duplicate-column behavior,
  numeric-column rejection, and result shapes.
• Remove retired CodeScene duplication gate rules and synchronize support
  policy baseline references with the 0.6 release line.
