Add get_browser_telemetry tool for archived session events

[yummybomb]

summary

• add get_browser_telemetry for archived browser telemetry, including deleted sessions
• support category filters, time windows, ascending/descending reads, and opaque offset pagination
• compact bulky event payloads while reporting omitted fields
• default ascending reads to the session creation time, or the Unix epoch when session metadata is unavailable, instead of the API's five-minute default
• distinguish an empty archive from telemetry that is currently disabled without treating the current config as historical evidence
• expand manage_browsers telemetry descriptions and the debug-browser-session prompt

The required SDK update and pagination migrations are isolated in #122. This PR is stacked on #122 and will be rebased onto main after it merges.

verification

• bun install --frozen-lockfile
• bunx tsc --noEmit
• Prettier check on changed source files
• mocked telemetry calls verify multi-category query serialization, full-session defaulting, payload compaction, omitted-field reporting, and the currently-disabled status

The repository does not have an automated test suite.
