feat: Centralize AI prompts into JSON templates (#882)

* centralize prompt management

* add changeset

* add variant key to determine prompt version

* update tests and add prompt manager test

* determine internal path, don't use projectRoot

* add promptManager mock

* detailed prompt docs

* add schemas and validator packages

* add validate prompts command

* add schema validation

* update tests

* move schemas to src/prompts/schemas

* use this.promptsDir for better semantics

* add prompt schemas

* version schema files & update links

* remove validate command

* expect dependencies

* update docs

* fix test

* remove suggestmode to ensure clean keys

* remove default variant from research and update schema

* now handled by prompt manager

* add manual test to verify prompts

* remove incorrect batch variant

* consolidate variants

* consolidate analyze-complexity to just default variant

* consolidate parse-prd variants

* add eq handler for handlebars

* consolidate research prompt variants

* use brevity

* consolidate variants for update subtask

* add not handler

* consolidate variants for update-task

* consolidate update-tasks variants

* add conditional content to prompt when research used

* update prompt tests

* show correct research variant

* make variant names link to below

* remove changset

* restore gitignore

* Merge branch 'next' of https://github.com/eyaltoledano/claude-task-master into joedanz/centralize-prompts

# Conflicts:
#	package-lock.json
#	scripts/modules/task-manager/expand-task.js
#	scripts/modules/task-manager/parse-prd.js

remove unused

* add else

* update tests

* update biome optional dependencies

* responsive html output for mobile
