[gem-team] Introduce specialized skills and guidelines to agents (#1271)

* feat(orchestrator): add Discuss Phase and PRD creation workflow

- Introduce Discuss Phase for medium/complex objectives, generating context‑aware options and logging architectural decisions
- Add PRD creation step after discussion, storing the PRD in docs/prd.yaml
- Refactor Phase 1 to pass task clarifications to researchers
- Update Phase 2 planning to include multi‑plan selection for complex tasks and verification with gem‑reviewer
- Enhance Phase 3 execution loop with wave integration checks and conflict filtering

* feat(gem-team): bump version to 1.3.3 and refine description with Discuss Phase and PRD compliance verification

* chore(release): bump marketplace version to 1.3.4

- Update `marketplace.json` version from `1.3.3` to `1.3.4`.
- Refine `gem-browser-tester.agent.md`:
  - Replace "UUIDs" typo with correct spelling.
  - Adjust wording and formatting for clarity.
  - Update JSON code fences to use ````jsonc````.
  - Modify workflow description to reference `AGENTS.md` when present.
- Refine `gem-devops.agent.md`:
  - Align expertise list formatting.
  - Standardize tool list syntax with back‑ticks.
  - Minor wording improvements.
- Increase retry attempts in `gem-browser-tester.agent.md` from 2 to 3 attempts.
- Minor typographical and formatting corrections across agent documentation.

* refactor: rename prd_path to project_prd_path in agent configurations

- Updated gem-orchestrator.agent.md to use `project_prd_path` instead of `prd_path` in task definitions and delegation logic.
- Updated gem-planner.agent.md to reference `project_prd_path` and clarify PRD reading.
- Updated gem-researcher.agent.md to use `project_prd_path` and adjust PRD consumption logic.
- Applied minor wording improvements and consistency fixes across the orchestrator, planner, and researcher documentation.

* feat(plugin): expand marketplace description, bump version to 1.4.0; revamp gem-browser-tester agent documentation with clearer role, expertise, and workflow specifications.

* chore: remove outdated plugin metadata fields from README.plugins.md and plugin.json

* feat(tooling): bump marketplace version to 1.5.0 and refine validation thresholds

- Update marketplace.json version from 1.4.0 to 1.5.0
- Adjust validation criteria in gem-browser-tester.agent.md to trigger additional tests when coverage < 0.85 or confidence < 0.85
- Refine accessibility compliance description, adding runtime validation and SPEC‑based accessibility notes- Add new gem-code-simplifier.agent.md documentation for code refactoring
- Update README and plugin metadata to reflect version change and new tooling

* docs: improve bug‑fix delegation description and delegation‑first guidance in gem‑orchestrator.agent.md

- Clarified the two‑step diagnostic‑then‑fix flow for bug fixes using gem‑debugger and gem‑implementer.
- Updated the “Delegation First” checklist to stress that **no** task, however small, should be performed directly by the orchestrator, emphasizing sub‑agent delegation and retry/escalation strategy.

* feat(gem-browser-tester): add flow testing support and refine workflow

- Update description to include “flow testing” and “user journey” among triggers.
- Expand expertise list to cover flow testing and visual regression.
- Revise knowledge sources and workflow to detail initialization, setup, flow execution, and teardown.
- Introduce comprehensive step types (navigate, interact, assert, branch, extract, wait, screenshot) with explicit wait strategies.
- Implement baseline screenshot comparison for visual regression.
- Restructure execution pattern to manage flow context and multi‑step user journeys.

* feat: add performance, design, responsive checks

* feat(styling): add priority-based styling hierarchy and validation rules

* feat: incorporate lint rule recommendations and update agent routing for ESLint rule handling

* chore(release): bump marketplace version to 1.5.4

* docs: Simplify readme

* chore: Add mobile specific agents and disable user invocation flags

* feat(architecture): add mobile agents and refactor diagram

* feat(readme): add recommended LLM column to agent team roles

* docs: Update readme

-- Project files: `./docs/PRD.yaml` and related files
-- Codebase patterns: Search and analyze existing code patterns, component architectures, utilities, and conventions using semantic search and targeted file reads
-- Team conventions: `AGENTS.md` for project-specific standards and architectural decisions

 # Workflow
 
 ## 1. Initialize

+## Execution
 - Activate tools before use.
-- Prefer built-in tools over terminal commands for reliability and structured output.
 - Batch independent tool calls. Execute in parallel. Prioritize I/O-bound calls (reads, searches).
-- Use `get_errors` for quick feedback after edits. Reserve eslint/typecheck for comprehensive analysis.
+- Use get_errors for quick feedback after edits. Reserve eslint/typecheck for comprehensive analysis.
 - Read context-efficiently: Use semantic search, file outlines, targeted line-range reads. Limit to 200 lines per read.
 - Use `<thought>` block for multi-step planning and error diagnosis. Omit for routine tasks. Verify paths, dependencies, and constraints before execution. Self-correct on errors.
-- Handle errors: Retry on transient errors. Escalate persistent errors.
-- Retry up to 3 times on verification failure. Log each retry as "Retry N/3 for task_id". After max retries, mitigate or escalate.
+- Handle errors: Retry on transient errors with exponential backoff (1s, 2s, 4s). Escalate persistent errors.
+- Retry up to 3 times on any phase failure. Log each retry as "Retry N/3 for task_id". After max retries, mitigate or escalate.
 - Output ONLY the requested deliverable. For code requests: code ONLY, zero explanation, zero preamble, zero commentary, zero summary. Return raw JSON per `Output Format`. Do not create summary files. Write YAML logs only on status=failed.
