Adds roku (Brightscript/BrighterScript and SceneGraph) support

[Fyb3roptik]

Summary

Adds full codesight support for Roku apps. Anchors project detection on the plain-text manifest file (the same file Roku itself uses), adds three new regex-based extractors (BrightScript, BrighterScript, SceneGraph XML), and wires all 8 detectors to map Roku idioms onto codesight's existing data model.

Closes #.

Layouts supported:

• Standard single-channel (~90% of Roku repos, the getting-started template + kernel-roku-style): manifest + source/ + components/ at the repo root.
• BrighterScript template (rokucommunity/brighterscript-template): bsconfig.json at root, channel rooted under src/. Detected as a single channel, not promoted to a monorepo.
• Multi-channel monorepo (explicit exception — large codebases that ship several branded channels via roku-deploy + gulp merging a shared common/ layer): each channel registered as its own workspace. Strict structural signal (no root manifest + roku-deploy in deps + common/ + ≥2 sibling-channel dirs with manifests) so an ordinary single-channel repo that happens to have roku-deploy is never mis-labeled.

Mapping:

• Routes — every child with an id in a Scene XML's <children> becomes a route. method = VIEW by default, upgraded to MODAL when a configurable navigation helper (default set covers ShowScreen, pushScreen, NavigateTo, showView, plus camelCase variants) is called with a literal true second arg. Works on projects with no helper at all.
• Schema — orm: "scenegraph" models from every component XML with a non-empty <interface>. Field types normalized (String→string, assocarray→object, node→node-ref, etc.).
• Components — one per SceneGraph XML; props = interface field ids.
• Libraries — .brs functions/subs; .bs adds classes, namespaces, enums, interfaces on top. Files under components/ are skipped (handler code, not libs).
• Middleware — observeField subscriptions, m.global.AddField registrations. BugsnagTask / RudderstackTask recognized when present.
• Graph — edges from <script uri="pkg:/..."> in XML + import "pkg:/..." in .bs, with a suffix-match resolver for nested channel layouts.
• Events — observed fields (system: scenegraph-observer) + Rudderstack event names (system: rudderstack).
• Config — Roku manifest keys surfaced as manifest.<name> pseudo env-vars.

Changes

• types.ts — adds Framework: "roku-scenegraph", ComponentFramework: "scenegraph", ORM: "scenegraph", language: "brightscript", EventInfo.system: "scenegraph-observer" | "rudderstack", and a CodesightConfig.rokuScreenHelpers?: string[] option.
• scanner.ts — adds .brs, .bs, .xml to CODE_EXTENSIONS; bare manifest added as a non-extension exception; roku_modules + .roku-deploy-staging added to IGNORE_DIRS; new hasRokuManifest(), detectBrighterScriptTemplateRoot(), and detectRokuMonorepo() helpers (structural common/ + ≥2 channels + roku-deploy signal); Roku language/framework/ORM + component framework branches; workspace discovery wires the monorepo detector in front of the generic depth-2 fallback.
• ast/extract-scenegraph.ts — new file. Parses <component>, <interface> fields + functions, <script uri> includes, <children>. Exposes extractSceneGraphComponent, extractMainSceneScreens, isSceneGraphXml.
• ast/extract-brightscript.ts — new file. extractBrightScriptFunctions, extractBrightScriptObservers, extractBrightScriptNavigationCalls (configurable helper names), extractBrightScriptShowScreenCalls (back-compat wrapper), extractBrightScriptGraphqlCalls, extractBrightScriptGlobalFields, extractBrightScriptRudderstackEvents, extractFindNodeBindings.
• ast/extract-brighterscript.ts — new file. extractBrighterScriptImports + extractBrighterScriptExports (classes, namespaces, enums, interfaces; composes with BrightScript extractor for functions/subs).
• detectors/routes.ts — new case "roku-scenegraph" branch + detectRokuScreens() helper. Children-first: <children> slots are the primary route surface; helper-call sites are optional enrichment that can flip VIEW→MODAL.
• detectors/schema.ts — new case "scenegraph" branch + detectSceneGraphSchemas() helper.
• detectors/components.ts — new case "scenegraph" branch + detectSceneGraphComponents() helper.
• detectors/libs.ts — .brs/.bs added to lib filter; dispatches to the new extractors. Filter now compares against the project-relative path, fixing a latent bug where any project hosted under a parent tests/ directory had all its lib files silently dropped.
• detectors/middleware.ts — emits observeField + m.global.AddField as custom middleware, BugsnagTask as error-handler, RudderstackTask as logging.
• detectors/graph.ts — extended to .brs/.bs/.xml; new extractSceneGraphImportsInline + extractBrighterScriptImportsInline with a suffix-match resolver for pkg:/... URIs.
• detectors/events.ts — extended to .brs/.bs; emits scenegraph-observer + rudderstack events.
• detectors/config.ts — surfaces manifest in configFiles and manifest keys as manifest.<name> env vars.
• README.md — adds BrightScript/BrighterScript to the Works-with line, updates the Supported Stacks table, adds a ## Roku / BrightScript / SceneGraph section that leads with the standard single-channel layout, documents the BrighterScript template variant, and calls out the multi-channel monorepo as an explicit exception with the structural signal described. Documents the rokuScreenHelpers config option.

Tests

New Roku SceneGraph Detection suite in tests/detectors.test.ts with four fixtures and assertions:

1. Kernel-roku-style single channel with no navigation helper at all — asserts two VIEW routes are derived from MainScene's <children> alone, repo is not flagged as a monorepo.
2. BrighterScript template (bsconfig.json + src/manifest) — asserts root is identified as the Roku channel, schemas + components include src/-rooted paths, not promoted to monorepo.
3. roku-deploy in deps but only one channel — asserts the structural signal does not fire, repo is single-channel.
4. Full multi-channel feature coverage — asserts VIEW/MODAL routes, scenegraph schemas with normalized field types, components + props, .brs + .bs lib exports, script-include + import dependency edges, manifest config surfacing, and observeField/m.global middleware.

Full suite: 58/58 pass (54 pre-existing + 4 new).

Real-world smoke tests:

• Synthetic kernel-roku-style channel (5 files, no navigation helper): detected as roku-scenegraph | scenegraph | brightscript, not a monorepo, 2 VIEW routes pulled from <children> alone.
• Multi-channel monorepo with 5 workspaces (common + 4 channels): still correctly detected as monorepo, 253 files scanned, 132K tokens saved per conversation.
