fix: remove inconsistent references to GitHub Actions sync workflow

Fixed documentation inconsistencies where old automatic sync approach
was still referenced despite moving to developer-side sync model:

CLAUDE.md:
- Changed "runs automatically via GitHub Actions" to "developer-side only"
- Updated sync process from "automatic pre-merge" to "developer-side"
- Fixed description of how sync works (manual via Task tool)

ADR-003:
- Updated decision from "pre-merge automatic" to "developer-side"
- Added provider-agnostic principle to decision rationale
- Replaced GitHub Actions workflow with native agent implementations
- Updated consequences to reflect manual approach

These changes ensure documentation correctly reflects our current
provider-agnostic, developer-side synchronization approach that
doesn't depend on external CI/CD systems.

+This repository uses **developer-side synchronization** to maintain consistency across all instruction files. When you update CLAUDE.md, ADRs, or developer agents, you must run the sync coordinator agent to update related files before committing.
 
 ### How It Works
 
-1. **Trigger**: When a PR modifies key instruction files:
+1. **Developer-side Trigger**: Before committing changes to instruction files:
    - `docs/decisions/*.md` (ADRs)
    - `CLAUDE.md` (this file)
    - `docs/developer-agents/*.md`
    - `.github/instructions/copilot-instructions.md`
+   - `.claude/agents/*.md` or `.github/chatmodes/*.md`
 
-2. **Sync Agent**: Runs automatically and:
-   - Analyzes changes in the PR
-   - Updates affected instruction files
-   - **Optimizes prompts**: Replaces code snippets with file references
-   - Commits changes to the same PR with `[skip-sync]` flag
-   - Preserves tool-specific features
+2. **Manual Sync Process**: Developer runs sync agent and:
+   - Uses Task tool with `subagent_type: agent-sync-coordinator`
+   - Agent analyzes git changes and recommends updates
+   - Developer applies suggested changes
+   - Commits all changes together in single commit
 
-3. **Single PR**: All changes (original + synchronized) are reviewed together
+3. **No CI/CD dependency**: Entirely developer-side, provider-agnostic

-- **PR complexity** - PRs may have additional commits from sync
-- **Potential noise** - Multiple sync runs if PR updated frequently
-- **CI complexity** - More complex GitHub Actions workflow
+- **Developer discipline required** - Developers must remember to run sync

-### Phase 2: GitHub Action Workflow
-Create `.github/workflows/sync-instructions.yml`:
-```yaml
-on:
-  pull_request:
-    types: [opened, synchronize]
-    paths: [relevant instruction files]
-
-jobs:
-  sync:
-    if: !contains(github.event.head_commit.message, '[skip-sync]')
-    steps:
-      - Run sync coordinator agent
-      - Commit changes to PR with [skip-sync] flag

+Create agent implementations for each AI tool:
+- **Claude**: `.claude/agents/agent-sync-coordinator.md`
+- **GitHub Copilot**: `.github/chatmodes/sync-coordinator.chatmode.md`
+- **Cursor IDE**: Sync reminder in `.cursor/rules/project-rules.mdc`

+Each implementation:
+- Uses git diff to identify changes
+- Maps source files to target files
+- Provides fast, targeted sync recommendations
+- No external API dependencies
