- User themes from $ZOT_HOME/themes/*.json with partial overrides
(colors, syntax, spinner) and dark/light fallback.
- /settings color-theme picker; selection persisted in config.json.
- Theme-only extensions: extension.json plus theme.json (or
themes/theme.json) load without spawning a subprocess.
- write-zot-themes built-in skill and docs/themes.md.
- README, extensions docs, and embedded docs index updated.
Single Go module, four top-level packages under packages/. Import
paths become github.com/patriceckhart/zot/packages/<name>; downstream
consumers can depend on individual packages without pulling the rest.
Layout:
packages/provider/ LLM clients + catalog
packages/provider/auth/ credential store + OAuth + login server
packages/core/ agent loop, sessions, cost
packages/tui/ terminal toolkit + chat view
packages/agent/ CLI wiring, system prompt
extensions/ extproto/ modes/ tools/ skills/ swarm/
sdk/ (was pkg/zotcore, package renamed zotcore -> sdk)
ext/ (was pkg/zotext, package renamed zotext -> ext)
internal/ and pkg/ removed. The internal/assets logo moved into
packages/provider/auth/assets.
Public Go SDK identifiers renamed:
pkg/zotcore (package zotcore) -> packages/agent/sdk (package sdk)
pkg/zotext (package zotext) -> packages/agent/ext (package ext)
This breaks Go-based extensions and embedders; the JSON wire protocol
for extensions and RPC is unchanged, so non-Go extensions, already-
built extension binaries, and zot rpc consumers are unaffected.
Docs, examples, and the built-in write-zot-extension skill updated
for the new paths and identifiers. Shadow-bug fixes in code samples
(ext := ext.New -> e := ext.New).
