fix(opencode): respect XDG data home - #1659
Conversation
Use XDG_DATA_HOME for default OpenCode discovery while preserving OPENCODE_DATA_DIR precedence and preventing fallback when it is explicitly empty. Document the precedence and add regression coverage. Co-authored-by: harunaltikaya <208832896+harunaltikaya@users.noreply.github.com>

- XDG-based default discovery. Confirmed that unset or empty
XDG_DATA_HOMEfalls back to$HOME/.local/share, while a configured value selects the correspondingopencodedirectory. - Override and regression coverage. Confirmed that explicit
OPENCODE_DATA_DIRhandling and ordered, deduplicated configured roots remain intact, with focused tests covering the new precedence behavior. - Documentation. Reviewed the updated environment-variable, OpenCode, getting-started, and adapter documentation for consistency with the implementation.

XDG/HOME-derived path as the default-path fallback, while describing
OPENCODE_DATA_DIR as the override used only when set; preserve the distinction
that an explicitly empty value disables fallback discovery.

- Clarified OpenCode fallback documentation. Reworded the overview to identify the XDG/HOME-derived directory as the fallback and
OPENCODE_DATA_DIRas the override, including the explicitly empty-value behavior. - Aligned documentation tables. Updated the environment-variable, overview, and OpenCode guide tables without changing the documented paths or runtime behavior.

In `@docs/guide/index.md`:
- Line 94: Update the documentation describing OPENCODE_DATA_DIR in the paths()
behavior so “when set” accurately reflects non-UTF-8 values: either change the
resolver to use env::var_os and honor such values, or explicitly document that
only valid UTF-8 values override the fallback while non-UTF-8 values are treated
as unset.

- Validated absolute XDG paths. Confirmed that relative
XDG_DATA_HOMEvalues are ignored and correctly fall back to$HOME/.local/share, matching the XDG Base Directory specification. - Added fallback regression coverage. Confirmed that separate tests cover unset and relative XDG values while preserving the existing configured and absolute-path behavior.
The focused OpenCode adapter suite passed all 42 tests, and the workspace Rust formatting check passed.
