fix: respect OPENCODE_CONFIG_DIR for personal skills lookup (#297)

[binbinao]

• fix: respect OPENCODE_CONFIG_DIR for personal skills lookup

The plugin was hardcoded to look for personal skills in ~/.config/opencode/skills, ignoring users who set OPENCODE_CONFIG_DIR to a custom path (e.g., for dotfiles management).

Now uses OPENCODE_CONFIG_DIR if set, falling back to the default path.

• fix: update help text to use dynamic paths

Use configDir and personalSkillsDir variables in help text so paths are accurate when OPENCODE_CONFIG_DIR is set.

• fix: normalize OPENCODE_CONFIG_DIR before use

Handle edge cases where the env var might be:

• Empty or whitespace-only
• Using ~ for home directory (common in .env files)
• A relative path

Now trims, expands ~, and resolves to absolute path.

---

Note

Ensures personal skills are resolved from OPENCODE_CONFIG_DIR when set, with robust path handling.

• Adds normalizePath to trim, expand ~, and resolve absolute paths for OPENCODE_CONFIG_DIR
• Derives configDir from env or default ~/.config/opencode, and sets personalSkillsDir from it
• Updates bootstrap/help text to reference ${configDir}/skills instead of hardcoded paths
• Adjusts find_skills empty-state message to show dynamic superpowersSkillsDir and personalSkillsDir
