refactor: rename `Kit` → `Pack` for clearer vendor-distribution semantics

Renames the extension-system primitive from "Kit" to "Pack" before any vendor
content has shipped publicly. "Pack" reads more naturally ("skill pack" is
already common language), differentiates from Claude Code's "plugin" noun,
and avoids the generic-SDK connotation of "kit".

Scope of rename:
- `Kit` namespace/types → `Pack` (runtime, CLI, config, telemetry)
- `KIT.yaml` → `PACK.yaml` file convention
- `.opencode/kits/` → `.opencode/packs/`; `active-kits` → `active-packs`
- Nested `SkillPack` type → `SkillGroup` / `skill_packs` field → `skill_groups`
  to resolve the "pack contains packs" nesting collision
- Telemetry events `kit_*` → `pack_*`
- File moves: `src/kit/` → `src/pack/`; `cli/cmd/kit.ts` → `cli/cmd/pack.ts`;
  `docs/{configure,develop}/kits.md` → `packs.md`
- CLI command group: `altimate-code kit ...` → `altimate-code pack ...`

No behavior change — pure rename + internal variable-shadow fix in
`allSkillsFromGroups` (inner loop variable `pack` → `group`).
