Fix SC2086 shellcheck warnings in compiler-generated shell scripts

[Copilot]

Shellcheck reported SC2086 warnings (unquoted variables causing potential word splitting/globbing) in compiler-generated .lock.yml files across all workflows.

Changes

Compiler code generation:

• pkg/workflow/artifacts.go - Quote path variables in find commands and $GITHUB_ENV redirects
• pkg/workflow/safe_jobs.go - Quote path variables in find commands and $GITHUB_ENV redirects
• pkg/workflow/sh/generate_git_patch.sh - Quote git ref variables ($BRANCH_NAME, $DEFAULT_BRANCH)

Before:

find /tmp/gh-aw/safeoutputs/ -type f -print
echo "VAR=value" >> $GITHUB_ENV
git show-ref --verify --quiet refs/heads/$BRANCH_NAME

After:

find "/tmp/gh-aw/safeoutputs/" -type f -print
echo "VAR=value" >> "$GITHUB_ENV"
git show-ref --verify --quiet "refs/heads/$BRANCH_NAME"

Test updates:

• pkg/workflow/safe_output_helpers_test.go - Update expected strings to match quoted format

All 68 workflows recompiled with fixes applied.

<issue_title>[task] Fix SC2086 shellcheck warnings in high-priority workflows (batch 1/3)</issue_title>
<issue_description>## Objective
Fix SC2086 shellcheck warnings (unquoted variables) in the first batch of affected workflows to improve code reliability and prevent potential word splitting issues.

Context

Static analysis identified 120+ instances of unquoted variables across 22 workflows. This task addresses the first batch of 7 high-traffic workflows. Part of discussion #3090.

Approach

Add double quotes around all variable references in shell script blocks within workflow markdown files.

Common Patterns to Fix

1. GITHUB_ENV assignments:

   # Before
   echo "VAR=value" >> $GITHUB_ENV
   
   # After
   echo "VAR=value" >> "$GITHUB_ENV"

2. Git commands:

   # Before
   git diff origin/$DEFAULT_BRANCH...$GITHUB_SHA
   
   # After
   git diff "origin/$DEFAULT_BRANCH...$GITHUB_SHA"

3. GitHub API calls:

   # Before
   gh api .../pulls/$PR_NUMBER/reviewers
   
   # After
   gh api .../pulls/"$PR_NUMBER"/reviewers

• .github/workflows/brave.md
• .github/workflows/changeset.md
• .github/workflows/ci-doctor.md
• .github/workflows/cli-version-checker.md

Acceptance Criteria

• All unquoted variables in shell script blocks have double quotes added
• No changes to logic or command behavior
• Workflows recompile successfully: gh aw compile --actionlint
• No SC2086 warnings remain in modified workflows
• All formatting and indentation preserved

Implementation Notes

• Only modify the source .md files, NOT the .lock.yml files
• Preserve all existing formatting and structure
• Test compilation after changes
• Verify no new issues introduced
