docs(skills): make skill references repo-relative

[davidahmann]

Problem

Several skill docs used machine-specific absolute paths (for example /Users/davidahmann/...), which breaks portability in other workspaces and CI environments.

Changes

• Replaced absolute repository path references with repo-relative references across skill docs.
• Updated intra-skill handoff links to use relative skill paths.
• Normalized path examples in workflow sections to remain executable across environments.

Validation

• make prepush-full
• ./.tmp/wrkr scan -path . --json > .tmp/command-anchor-scan.json

Fix relative path to sibling gait style reference

The converted reference path gait/product/PLAN_v1.md resolves under the current repo (wrkr/gait/...), but the original absolute path pointed to a sibling checkout (.../Projects/gait/...), which should become ../gait/product/PLAN_v1.md. In environments where wrkr and gait are side-by-side (the layout implied by the previous path), this change prevents the workflow from finding the style reference and silently drops intended plan-structure guidance.
