feat: TUI, iconify search, AI-usable, configs

[Blankeos]

Lots of updates (note the version will be 1.0.2), the screenshots are just in dev atm.

• Rebuilds the interactive CLI into a modular TUI flow with dedicated views/popups for add, delete, rename, help, and main search/navigation.
• Adds full Iconify integration via a shared client and new iconmate iconify commands (search, collections, collection, get) with script-friendly text/JSON output.
• iconify integration is also AI-usable, they can use just commands like bash.
• Introduces local/global config loading and precedence (folder, preset, template, SVG viewer command), including validation + warning behavior.
• Adds config schema tooling (config-gen) and generated schema artifacts for editor support (iconmatelocal.schema.json, iconmateglobal.schema.json).
• Improves npm binary bootstrap/install behavior and refreshes docs/branding assets, with extra integration-test coverage for add-flow edge cases.

Review

• LGTM for merge with one minor nit.
• nit Splitting lines by ';' in delete/rename/remove functions may discard comments on mixed export lines, e.g. at src/utils.rs:544, src/utils.rs:714, src/main.rs:773. Safe if index.ts is exports-only.
• Optional caution: duplicate check skips when parsing custom output templates fails (src/main.rs:595), possibly allowing overlooked duplicates. Low risk.
• Validation: ran cargo test all 62 tests passed.
• Rating: 4.7/5
• Confidence: 86% (high)
  Looks good for merge overall. I reviewed the latest delta (b421a56) and ran the suite (cargo test, 62 passed).
• Merge readiness: no blockers found.
• Minor nit (non-blocking): index rewrite logic can drop non-export fragments (like trailing comments) when a line contains both an export and extra text because only parsed export statements are re-emitted (src/main.rs:773, src/utils.rs:544, src/utils.rs:714).
• Minor hardening note: duplicate-conflict validation is skipped when a custom output template cannot be parsed as the expected TS export shape (src/main.rs:595), so custom templates may bypass alias/target conflict checks.
• Good changes: conflict checks now happen before writes, concatenated-export handling is improved, and TUI cleanup is safer via RAII guard.
• Rating: 4.7/5
• Confidence: 86% (high)
