Unify tool access and harden worker operations

[rohan-patnaik]

Summary

• remove tool-level premium gating and align local dev behavior to bypass limits automatically in local dev mode
• simplify tools UI by removing the dev bypass toggle and updating usage/capacity copy
• remove workflow/team surfaces and related Convex/web wiring no longer used
• harden worker tooling (clearer numeric parsing errors, safer unlock password handling, dynamic signature stamp sizing, unique OCR temp files, HTML-to-PDF filename generation)
• update docs and worker assets to match runtime behavior

Validation

• npm --prefix apps/web run lint
• npm --prefix apps/web run test
• pytest -q apps/worker/tests
• coderabbit review --plain --type uncommitted --base main (one full run; follow-up rerun blocked by rate limits)

Summary by CodeRabbit

• New Features

  • Expanded tool catalog to 27 unified tools including PDF conversions (Word, PowerPoint, Excel, HTML, JPG), editing, signing, organizing, and OCR capabilities.
  • All tools now available across all plans; premium is capacity-based (higher throughput and daily limits) rather than tool-restricted.

• Removed Features

  • Workflows, Teams, and workflow studio removed.
  • Premium-only tool restrictions eliminated.

• Documentation

  • Updated architecture and QA docs to reflect 27-tool unified catalog.

📝 Walkthrough

Walkthrough

This PR consolidates the platform from a premium-tiered, workflow-studio architecture to a unified 27-tool catalog with capacity-based premium. It removes team/workflow management modules, eliminates premium-only tool restrictions, expands worker tool support with office conversions and OCR capabilities, and updates the public API surface accordingly.

Changes

Cohort / File(s)	Summary
Backend Tool & Job System apps/web/convex/jobs.ts, apps/web/convex/schema.ts	Replaced PREMIUM_ONLY_TOOLS with a broader SUPPORTED_TOOLS set containing 27 tools; removed devBypass mutation argument and premium enforcement logic; added tool validation on job creation; removed workflows, teams, and teamMembers database tables.
Error Definitions apps/web/convex/lib/errors.ts, apps/web/src/lib/errors.ts	Removed USER_LIMIT_PREMIUM_REQUIRED error code from FRIENDLY_ERRORS constant in both backend and frontend, narrowing allowed error types.
Workflow & Team Infrastructure apps/web/convex/lib/workflow_compiler.ts, apps/web/convex/lib/workflow_spec.ts, apps/web/convex/teams.ts, apps/web/convex/workflows.ts	Deleted entire workflow compiler, workflow specifications, and team management modules; removed all related type definitions, constants, and 4+ exported queries/mutations for workflow and team operations.
Public API Surface apps/web/src/lib/convex.ts	Removed WorkflowSummary, TeamMemberSummary, and TeamSummary type exports; removed workflows and teams API namespaces; removed devBypass field from jobs.createJob input.
Frontend Pages apps/web/src/app/page.tsx, apps/web/src/app/tools/page.tsx, apps/web/src/app/workflows/page.tsx, apps/web/src/app/usage-capacity/page.tsx	Removed ToolCard badge prop and workflow studio page (975 lines); expanded tools page with 17+ new/renamed tool IDs, textarea field type, and removed tier badge UI; updated home page tool shelf descriptions and removed workflow references; updated usage page copy and removed premium-only error references.
Header & Navigation apps/web/src/components/SiteHeader.tsx, apps/web/src/middleware.ts	Removed Workflows navigation link; updated supporter banner messaging; made middleware auth handler async.
Worker Python Implementation apps/worker/zenpdf_worker/tools.py, apps/worker/zenpdf_worker/worker.py	Added 9 new tool functions (word/powerpoint/excel-to-pdf, pdf-to-powerpoint, sign-pdf, edit-pdf, organize-pdf, ocr-pdf, scan-to-pdf); enhanced overlay and OCR logic; replaced web-to-pdf with html-to-pdf dispatch; expanded TOOL_OUTPUT_SUFFIXES mappings; added 110+ lines of new tool implementations and 100+ lines of dispatch logic updates.
Worker Dependencies & Tests apps/worker/Dockerfile, apps/worker/requirements.txt, apps/worker/tests/test_tools.py	Added libreoffice, ocrmypdf, tesseract-ocr system packages; added python-pptx==1.0.2 dependency; introduced 9 new test functions covering edit, organize, sign, ocr, and conversion tools (133+ new test lines).
Configuration & Environment apps/web/.env.example	Added ZENPDF_DEV_MODE=1 environment variable for local development bypass.
Documentation README.md, docs/ARCHITECTURE.md, docs/OBSERVABILITY.md, docs/PRD.md, docs/QA.md, docs/RELEASE_CHECKLIST.md, docs/SECURITY.md, docs/SELF_HOST.md, docs/TOOL_TECHNIQUES.md	Updated README with 27-tool scope; removed workflow/team references from architecture; clarified logging no longer requires teamId; rewrote tool techniques for 27-tool catalog alignment; updated QA tool expectations and output naming; updated security policy to remove workflow scope; updated release checklist to reference tools instead of workflows; added dev-mode bypass documentation; removed premium-only tool distinctions from PRD.

Sequence Diagram(s)

No sequence diagrams generated — the architectural change simplifies control flow (removal of workflow abstraction layer) rather than introducing new multi-component interactions, and the core job→tool→worker dispatch is straightforward.

Poem

🐰 Twenty-seven tools now shine as one,
No workflows to weave, just jobs to be done!
Teams took their leave, and tiers lost their gate,
A simpler, swifter PDF fate. ✨📄
