Bump to 0.2.0 and make max tool-call iterations configurable

The 8-iteration-per-turn cap was hardcoded from before this session's feature work and
too tight for genuine multi-file tasks, causing "Max tool-call iterations reached" on
legitimately multi-step work. Raised the default to 25 and made it configurable via
`locode config set maxIterations <n>` / $LOCODE_MAX_ITERATIONS, mirroring the existing
contextWindow config pattern.

Also bumps the version to 0.2.0 (package.json, --version, and the MCP client's
self-reported identity) to reflect the substantial feature additions since 0.1.0.
