chore(release): v0.2.0

[RasputinKaiser]

Summary

Release cut for v0.2.0 per RELEASING.md.

Bump rationale

Minor bump (0.1.0 → 0.2.0) at 0.x — driven by:

• feat: — /insights-context skill with cross-referenced friction resolution (Added section)
• Several user-visible Added entries (cliPrint helpers, swallow() helper, clearAllBaseToolsCache invalidation, reconcilerShims extraction, isToolConcurrencySafe extraction)

What changed in this commit

• package.json: 0.1.0 → 0.2.0
• CHANGELOG.md: moved [Unreleased] contents into new ## [0.2.0] - 2026-06-25 section; left [Unreleased] empty
• CHANGELOG.md: added [0.2.0] compare link; updated [Unreleased] to compare v0.2.0...HEAD

Release contents (since v0.1.0)

21 commits spanning the code-quality refactor arc:

• Added — cliPrint/cliPrintWarn/cliPrintError helpers (241 of 248 suppressions migrated); swallow() helper for observable fire-and-forget catches; clearAllBaseToolsCache + plugin reload invalidation; reconcilerShims.ts for react-reconciler type augmentations; shared isToolConcurrencySafe() helper; /insights-context skill
• Changed — 77 NCODE_BUILD_MODE/USER_TYPE direct env reads migrated to isInternalBuild(); modifiers.ts rewritten to lazy createRequire; unnecessary PermissionMode cast removed
• Fixed — modifiers-napi build failure (lazy require); silent failures in JWT decode, LSP tool decodeURIComponent, image-processor-napi load, and agentMemorySnapshot read now log at debug level; REPL and errorUtils/compact TODOs resolved
• Removed — Dead stub N-API packages (image-processor-napi, color-diff-napi, modifiers-napi, url-handler-napi) from package.json; orphaned rust/py_repl_host/ crate + BUCK artifact; stale /mlstore/src/noumena/ path from packageAudit.mjs; 11 stale @ts-expect-error comments; 98 scattered biome-ignore noConsole comments
• Docs — release process, build mode, Rust minimum version, Kimi K2.7 Coder selection, and prompt-category cast explanations
