Complete v2 rewrite: clear repository and apply ni/v2 commits

[Copilot]

Replaces the entire repository with the v2 rewrite from the ni/v2 branch. The branch was cleared and rebuilt with commits preserving their individual history.

Changes

• Repository reset: All v1 files deleted in single commit
• v2 architecture applied: 6 commits from ni/v2 cherry-picked in chronological order:
  • Initial v2 foundation with Svelte components, agent system, and provider setup
  • Nix flake configuration for reproducible builds
  • Agent manager with tool integrations (dataview, search, note reading)
  • Removal of intermediate v2 subdirectory artifacts

Architecture shifts

• Frontend: Svelte 5 with runes, TanStack Query for state management
• Agent system: ObsidianChatManager with tool calls for vault operations
• Build: Vite + esbuild, Nix flake for dev environment
• Database: Dexie (IndexedDB) for chat persistence

Final history: [main base] → [clear commit] → [6 ni/v2 commits]

Original prompt

Goal

Complete the v2 rewrite by deleting all content on the copilot/clear-repository-for-v2-rewrite branch and rebasing the ni/v2 commits onto it.

Current State

• PR Create ni/v2-with-history branch preserving main history with v2 rewrite #197 created the branch copilot/clear-repository-for-v2-rewrite from main
• The branch still has all the original main content
• We need to delete everything and apply the ni/v2 commits

Steps to Complete

1. Delete ALL existing files on the copilot/clear-repository-for-v2-rewrite branch and commit with message "chore: clear repository for v2 rewrite"
2. Rebase/cherry-pick all commits from ni/v2 onto this branch, preserving individual commits

Commits from ni/v2 to apply (in chronological order):

1. fe3e5c5 - "save" (Dec 12, 2025)
2. f73e20b - "updated nix" (Dec 15, 2025)
3. 7675f63 - "flake update" (Dec 16, 2025)
4. 76ed2d5 - "stuff" (Dec 17, 2025)
5. 8a79121 - "so far so good" (Dec 22, 2025)
6. 2c7db75 - "chore: remove sym" (Dec 22, 2025)

Expected Final Branch History

[main history] → [delete all files commit] → [6 ni/v2 commits in order]

Technical Approach

1. First, delete all files and commit
2. Then cherry-pick each commit from ni/v2 in order:

   git cherry-pick fe3e5c5
   git cherry-pick f73e20b
   git cherry-pick 7675f63
   git cherry-pick 76ed2d5
   git cherry-pick 8a79121
   git cherry-pick 2c7db75
   

The final PR should show the complete v2 rewrite ready to merge into main.
