feat: OR filter for project board views

[BigLep]

Summary

• OR query support on project boards: Enter queries like cycle:202605-2 biglep (-status:"🎉 Done") OR (-last-updated:1days) in the filter bar to see merged results from multiple branches in a single view — no more switching between views during standup.
• Configurable board patterns: New Options setting lets users specify which project boards get OR filter support via glob-style URL patterns (defaults to https://github.com/orgs/FilOzone/projects/*).
• Version bump to 0.3.0

How it works

The extension injects a main-world script that monkey-patches window.fetch on matching project board pages. When the filter bar contains OR syntax, it intercepts GitHub's internal paginated_items API call, splits the query into per-branch fetches, deduplicates items by ID, merges the results, and returns them to GitHub's React app — which renders them natively with no custom UI.

Files

New files	Purpose
extension/src/content/board-filter/board-filter-main.ts	Content script entry point, config gate
extension/src/content/board-filter/board-data-injector.ts	Main-world fetch interceptor, branch fetching, merge
extension/src/content/board-filter/or-query-parser.ts	Parse OR syntax into prefix + branches
extension/src/content/board-filter/result-merger.ts	Deduplicate and merge multi-branch responses
extension/src/content/board-filter/memex-api.ts	Type definitions for GitHub's internal memex API

Test plan

• Load extension, navigate to FilOzone/projects/14/views/20
• Enter OR query: cycle:202605-2 biglep (-status:"🎉 Done") OR (-last-updated:1days) — verify merged results, no duplicates
• Enter non-OR query (e.g. biglep) — verify native filtering unchanged
• Enter invalid OR syntax (e.g. ((nested))) — verify native fallback, no errors
• Test on "All" view (/views/2) with large item set — verify pagination works
• Verify existing issue/PR sidebar features still work
• Check Options page shows "OR filter for project boards" textarea with default pattern

Pull request overview

Adds OR-condition filtering support on GitHub Project board views by injecting a main-world fetch interceptor that fans out /memexes/{id}/paginated_items requests per OR-branch, then merges/dedupes results so GitHub’s native React UI renders the combined set. It also introduces an Options setting to gate the feature by board URL patterns and bumps the extension version to 0.3.0.

Changes:

• Add new project-board content script + injected main-world fetch interceptor for OR-query fanout/merge.
• Add configurable “OR filter for project boards” URL patterns in Options + config loader helpers.
• Add/refresh spec docs, build pipeline entries, and version bumps.
