Added

• --extras jvm-stack-trace highlights JVM stack traces (Java, Kotlin, Scala, etc.) • TAILSPIN_EXTRAS environment variable to set extras without the --extras flag

Performance

• Cache ANSI style prefixes in a thread-local, avoiding per-line allocation in the render pipeline

Fixed

• Theme parse and read errors now include the path of the offending file • Reject unknown fields in theme.toml so they surface as errors instead of being silently ignored • --exec no longer tears down the pager the moment the spawned subprocess exits • Kill the pager when tailspin exits due to a stream error, instead of leaving it orphaned • Overriding builtin keywords in theme.toml should always take precedence over the builtin ones (#267)
