docs: Update REPOSITORIES.md with correct package names

[Xhristin3]

Problem Statement

REPOSITORIES.md references outdated package names:

• "streaming-sdk" should be "xstreamroll-sdk"
• "stream-processing" should be "xstreamroll-processing"
• References npm install but api/ uses pnpm (pnpm-lock.yaml exists)

Evidence

## 3. Streaming SDK (`/streaming-sdk`) — actual directory is xstreamroll-sdk
## 4. Stream Processing (`/stream-processing`) — actual directory is xstreamroll-processing

Impact

New contributors following REPOSITORIES.md will cd into non-existent directories. The pnpm/npm discrepancy causes install failures for the api package.

Proposed Solution

1. Update all package directory references to match actual names
2. Document that api/ uses pnpm, other packages use npm
3. Verify all setup commands work when followed exactly

Acceptance Criteria

• Directory paths match actual filesystem names
• Package manager instructions match each package's lockfile
• Setup commands verified working

File Map

• REPOSITORIES.md — corrections

Hi there, I'd like to work on this issue.

[Xhristin3]

Just for the record: this is now resolved on main via commit 91ec738 — docs(repo): fix repository package names — which renames /streaming-sdk → /xstreamroll-sdk and /stream-processing → /xstreamroll-processing in REPOSITORIES.md, and switches the api/ package-manager commands from npm to pnpm. Closing the related PR (#266) as superseded. Thanks @AnnieIj! ✅
