style: rename catch (err|error) identifiers to catch (e)

Mechanical rename across 11 files to match the CLAUDE.md
catch-binding convention. 12 catch clauses converted; body
references renamed including inside template literal interpolations.
Property keys and member-access expressions (logger.error,
console.error) are left untouched.

tsgo --noEmit clean post-sweep.
