* Add optional rationale parameter to update_issue_type tool
Add an optional `rationale` string parameter (max 280 chars) to the
`update_issue_type` MCP tool. When provided, the type is sent as an
object `{"name": "...", "rationale": "..."}` to the REST API,
enabling agents to explain their classification decisions. When omitted,
existing behavior is preserved (type sent as a plain string).
This supports the agent rationale experiment for type mutations. The
parameter is always visible in the schema — the API gracefully ignores
the rationale when the server-side feature flag is disabled.

* Fix set_issue_fields mutation: use correct inline fragments for IssueFieldValue union
The mutation response struct used a single inline fragment
'... on IssueFieldDateValue' with a 'Name' field that doesn't exist
on that type (only IssueFieldSingleSelectValue has 'name'). This
caused GraphQL validation to fail with:
Field 'name' doesn't exist on type 'IssueFieldDateValue'
Since GraphQL validates the entire document (including response
selection sets) before executing any operation, the mutation never
fired at all — no fields were ever set regardless of input.
Fix by adding correct inline fragments for all four union types:
- IssueFieldTextValue (value)
- IssueFieldSingleSelectValue (name)
- IssueFieldDateValue (value)
- IssueFieldNumberValue (value)
* Update test mock to match corrected inline fragments
* Update handler_test.go formatting

* initial OSS granular PRs and issues toolsets
* update docs
* refactor: reuse existing helpers in granular toolsets
Refactor granular issue and PR tools to delegate to existing tested
helper functions instead of reimplementing logic from scratch:
- Sub-issue tools (add/remove/reprioritize) now delegate to existing
REST-based AddSubIssue, RemoveSubIssue, ReprioritizeSubIssue helpers
- PR review tools (create/submit/delete) now delegate to existing
CreatePullRequestReview, SubmitPendingPullRequestReview,
DeletePendingPullRequestReview helpers (fixes viewer filtering bug)
- Review comment tool now uses viewer-safe pattern from
AddCommentToPendingReview (query viewer, filter by author, validate
PENDING state, pass PullRequestReviewID)
- Fix milestone param to use RequiredInt instead of float64 cast
- Fix line/startLine params to use OptionalIntParam
- Draft state tool uses typed GraphQL inputs matching existing patterns
- Remove duplicate GraphQL types and helper functions
- Add toolsnap tests for all 20 granular tools
- Update generated docs

* refactor: use feature flags instead of separate granular toolsets
Place granular tools in existing issues/pull_requests toolsets with
FeatureFlagEnable, instead of creating separate issues_granular and
pull_requests_granular toolsets. This is simpler and uses the existing
feature flag infrastructure to switch between consolidated and
granular tool variants at runtime.

* fix: address review feedback on granular toolsets
- Fix REST response handling: capture resp, close body, use ghErrors
helpers in issueUpdateTool, prUpdateTool, GranularCreateIssue, and
GranularRequestPullRequestReviewers
- Add FeatureFlagDisable on consolidated tools (IssueWrite, SubIssueWrite,
UpdatePullRequest, PullRequestReviewWrite, AddCommentToPendingReview)
so they are hidden when granular variants are active
- Use OptionalStringArrayParam for assignees, labels, reviewers instead
of manual loop that silently dropped non-string elements
- Fix side/startSide empty string leak: pass nil pointer when absent
instead of pointer to empty string in GraphQL mutations
- Fix milestone minimum from 0 to 1 to match RequiredInt rejection of 0
- Return MinimalResponse {id, url} instead of full JSON objects
- Fix RequiredParam[bool] rejecting draft=false by using presence check
- Add handler tests for update_pull_request_draft_state (draft + ready)
and add_pull_request_review_comment with full GraphQL mocking

* fix: address review feedback on granular toolsets
- Fix translation keys to use ALL_CAPS convention (strings.ToUpper)
- Fix assignees/labels clearing: check key presence instead of len==0
- Extract AddCommentToPendingReviewCall helper to deduplicate GraphQL
logic between consolidated and granular tools
- Add missing granular tools: resolve_review_thread, unresolve_review_thread
(were in pull_request_review_write but had no granular replacements)
- Add handler tests for new resolve/unresolve tools
