chore(release): 1.9.0 [skip ci]

# [1.9.0](https://github.com/asepharyana/zesdex/compare/v1.8.0...v1.9.0) (2026-07-14)

### Bug Fixes

* **workflow:** import Color style for improved agent state rendering ([472c597](https://github.com/asepharyana/zesdex/commit/472c597c5e4ab12808a6bcd1899628bc7ab77186))

### Features

* **agent:** refine cognitive cycle plan with structured phases for exploration, planning, and execution ([c5253b2](https://github.com/asepharyana/zesdex/commit/c5253b2ca359d4dbed9445e04f1dec1a6bb37e8f))
