Rename catch variables to follow naming convention

[trask]

Trying to get ahead of the review bot to try to start reducing the number of those PRs...

Rename catch clause variables across the repo:

• exception -> e for used exception catch variables
• exception -> t for used Throwable catch variables
• throwable -> t for used Throwable catch variables
• unused catch parameters -> ignored

[Copilot]

Pull request overview

This PR standardizes catch clause variable names across the codebase to match the repository’s catch-variable naming convention (e.g., e for used exceptions, t for used Throwable, and ignored for intentionally unused catches), reducing style-only review noise.

Changes:

• Renamed used Exception/RuntimeException catch variables to e.
• Renamed used Throwable catch variables to t.
• Renamed intentionally-unused catch variables to ignored in many locations.
