chore: remove CLAUDE.md from public repo

Internal development rules do not belong in a public repository.
File is kept locally and added to .gitignore.

-# CodeBurn Development Rules
-
-## Verification
-- NEVER commit without running locally first and confirming it works
-- Run `npx tsx src/cli.ts report` and `npx tsx src/cli.ts today` to verify changes before any commit
-- For dashboard changes: run the interactive TUI and visually confirm rendering
-- For new features: test the happy path AND edge cases (empty data, missing config, pipe mode)
-- For any PR touching parser, source cache, or data aggregation: run cached vs uncached comparison before merge. Costs must match within $0.10. Use: `parseAllSessions(range, 'all', { noCache: false })` vs `parseAllSessions(range, 'all', { noCache: true })` and compare totals. A mismatch means the cache is serving stale or incorrect data
-
-## Code Quality
-- Clean, minimal code. No dead code, no commented-out blocks, no TODO placeholders
-- No emoji anywhere in the codebase
-- No em dashes. Use hyphens or rewrite the sentence
-- No AI slop: no "streamline", "leverage", "robust", "seamless" in user-facing text
-- No unnecessary abstractions. Three similar lines > premature helper function
-- No magic numbers. Extract layout offsets, column widths, thresholds, timeouts, and any value used in a calculation into a named `const` at module scope. Inline literals are only OK for universally understood constants (0, 1, 100 for percent). If a number appears in a formula like `pw - bw - 31`, the `31` must be a named constant.
-
-## Accuracy
-- Every user-facing number (cost, tokens, calls) must be verified against real data
-- LiteLLM pricing model names must match exactly. No guessing model IDs
-- Date range calculations must be tested with edge cases (month boundaries, billing day > days in month)
-
-## Style
-- TypeScript strict mode. No `any` types
-- No comments unless the WHY is non-obvious
-- Imports: node builtins first, then deps, then local (separated by blank line)
-- Single quotes, no semicolons inconsistency (follow existing: no trailing semicolons in most files)
-
-## Git
-
-### Branching (strict)
-- NEVER commit directly to main. All work happens on branches
-- Branch naming: `feat/<name>`, `fix/<name>`, `chore/<name>`, `docs/<name>`
-- Merge to main ONLY after: tests pass, CLI verified, manual testing done
-- npm publish ONLY from main after merge
-- Tag releases: `git tag v0.X.0` after publish
-
-### Creating a branch
-```bash
-git checkout main && git pull origin main
-git checkout -b feat/my-feature
-# work, test, iterate
-npx vitest run
-npx tsx src/cli.ts report
-# when ready:
-git checkout main && git merge feat/my-feature
-git push origin main
-```
-
-### Handling external PRs
-- NEVER rewrite a contributor's changes on your own branch. Always merge THEIR branch
-- Add your improvements as separate commits on top of their branch, not as replacements
-- This preserves their authorship in git history so GitHub shows them as a contributor
-```bash
-gh pr checkout <number>           # checkout PR locally
-npx vitest run                    # test their code
-npx tsx src/cli.ts report         # manual verification
-# apply patches if needed, commit on their branch
-git checkout main
-git merge <branch>                # preserves their authorship
-git push origin main
-gh pr comment <number> --body "Merged, thanks!"
-```
-
-### What gets committed
-- Source code: `src/`, `tests/`
-- Config: `package.json`, `tsconfig.json`, `tsup.config.ts`, `.gitignore`
-- Docs: `README.md`, `CHANGELOG.md`, `LICENSE`, `CLAUDE.md`
-- Assets: `assets/`
-- NEVER commit: `.env`, secrets, keys, planning docs (`docs/superpowers/`), IDE config, logs, `.DS_Store`
-- Check `git status` before every commit. Stage specific files, never `git add -A` or `git add .`
-
-### Commit rules
-- Commits from: AgentSeal <hello@agentseal.org>
-- NEVER add Co-Authored-By lines
-- NEVER include personal names or usernames in commits
-- Small, focused commits. One feature per commit
-- Test locally before every commit
-
-### Public-facing language (commits, PRs, release notes, README)
-- Commits and release notes are public. Write like you'd publish them.
-- NEVER use words like "steal", "stealing", "copy", "rip off", "inspired by" in commit messages
-- Describe what the code does, not where ideas came from
-- If you must credit prior art, do it in code comments or docs, not commit messages
-- No snark, no filler, no self-deprecation. Treat each commit as a product statement
