Add interactive TUI mode

[horstf]

Summary

• Add -i flag that launches a Bubble Tea interactive TUI for browsing gRPC methods, previewing JSON request templates, and copying them to clipboard
• Refactor ListMethods() to be side-effect free (no stdout printing), moving display logic to the caller in main.go
• Add automatic gRPC reflection stream reconnection on EOF, fixing failures when making multiple sequential operations

New packages

• pkg/tui/ — Bubble Tea TUI with filterable list view and scrollable JSON preview
• pkg/clipboard/ — Cross-platform clipboard write via pbcopy/xclip/clip.exe

Test plan

• make build compiles successfully
• make test — all existing tests pass
• ./goshape -host localhost -port 50051 -list-methods still works (non-interactive)
• ./goshape -host localhost -port 50051 -i launches TUI
• Method list is filterable by typing
• Selecting a method shows JSON template preview
• Enter on preview copies to clipboard
• Esc returns to list, q quits

CI Failure: Go Version Mismatch

The CI is failing at the Lint step before tests even run:

Error: can't load config: the Go language version (go1.24) used to build
golangci-lint is lower than the targeted Go version (1.26)

Root cause: .github/workflows/ci.yml line 22 sets go-version: '1.24.x' but go.mod requires Go 1.26. I cannot modify workflow files directly (GitHub App permissions), but the fix is a one-line change: Fix this →

CI Steps That Ran

Step	Result
Build (make build)	✅ Passed
Vet (make vet)	✅ Passed
Lint (golangci-lint run ./...)	❌ Failed — Go 1.24 vs 1.26 mismatch
Unit tests	⏸ Never ran
Integration tests	⏸ Never ran

Test Files Found

The test suite covers:

• pkg/reflection/client_test.go — TestNewClient, TestListMethods, TestClientWithCancelledContext, TestGetMethodInputType, TestGenerateRequestTemplate, TestSecureConnection
• pkg/reflection/template_test.go — TestGenerateDefaultValue, TestGenerateMessageTemplate, TestFormatJSON
• pkg/reflection/descriptor_test.go — descriptor registry tests
• pkg/reflection/integration_test.go — integration tests (require live server, tagged integration)

The new packages added in this PR (pkg/tui/ and pkg/clipboard/) do not have tests yet.

Next Steps

1. Fix CI: Update go-version: '1.24.x' → '1.26.x' in .github/workflows/ci.yml
2. Once CI is fixed, tests should run automatically on the next push

Fixed golangci-lint Configuration

• Gather context & check CI status
• Read workflow and lint configuration files
• Identify root cause of lint failures
• Fix .golangci.yml to use v1-compatible format
• Commit and push fix

Root Cause

The CI installs golangci-lint@latest which resolves to v1.64.8, but .golangci.yml declared version: "2" (golangci-lint v2 format), causing:

Error: you are using a configuration file for golangci-lint v2 with golangci-lint v1: please use golangci-lint v2

Fix Applied (commit 3eed9a2)

Converted .golangci.yml from v2 → v1 format:

What changed	v2 format	v1 format
Version declaration	version: "2"	(removed)
Formatters section	formatters: enable: [gofmt, goimports]	Moved to linters.enable
Settings key	linters.settings	linters-settings
File exclusions	issues.exclusions.paths	issues.exclude-files
Rule exclusions	issues.exclusions.rules	issues.exclude-rules

All linters are preserved — gofmt and goimports are valid linters in golangci-lint v1.

Note: If you'd prefer to use golangci-lint v2 long-term, update the CI install command from golangci-lint/cmd/golangci-lint@latest to golangci-lint/v2/cmd/golangci-lint@latest in .github/workflows/ci.yml. This would allow keeping the v2 config format.
