fix: Windows deployment - broken symlinks, missing packages, dep scanner false positives

[hafocreative-official]

Description

When building GoClaw from source on Windows via Docker Desktop, all 5 core skills show "Missing deps" on the Skills page. This PR fixes 3 root causes.

Changes

1. Dockerfile - Missing skill packages + Windows compatibility

• Added packages to ENABLE_FULL_SKILLS install:
• • poppler-utils, bash (apk)
• • pdfplumber, pdf2image, anthropic (pip)
• • CRLF fix: sed -i 's/\r$//' on entrypoint script at build time
• • Symlink fix: On Windows, git clone with core.symlinks=false (default) converts symlinks to text files or drops them entirely. Skills docx/pptx/xlsx have scripts/office -> ../../_shared/office symlinks that break. The new RUN step copies _shared/office directly into each skill's scripts/ dir when the symlink is missing.

2. internal/skills/dep_scanner.go - False positive missing deps

Two issues caused the dep scanner to falsely report local modules as missing pip packages:

• Nested subdirectories: office/helpers/ and office/validators/ are subdirectories of scripts/office/. Files inside office/ do from helpers import ... - these are intra-package imports. The scanner only tracked first-level subdirs of scripts/ as local modules, so helpers and validators were reported as pip:helpers, pip:validators.
• • Self-referencing: skill-creator scripts do from scripts import utils - referencing their own parent directory. The scanner didn't treat scripts (the dir basename) as a local module.

3. .gitattributes - Prevent CRLF in shell scripts

Ensures *.sh and docker-entrypoint.sh always use LF line endings regardless of the developer's OS.

Testing

• Built and deployed on Windows 11 + Docker Desktop
• • All 5 core skills (docx, pdf, pptx, xlsx, skill-creator) show Active status
• • Seeder logs confirm: async dep check complete checked=5 with no skill deps missing warnings
