Added nullable posts.auto_excerpt and posts.reading_time columns

[louisghost]

Summary

• Adds nullable posts.auto_excerpt and posts.reading_time columns (DDL only, { algorithm: 'auto' }) so automatic excerpt and reading time can later be stored instead of recomputed on every Posts API response.
• Updates schema.js and the schema integrity hash to match.
• Strips auto_excerpt from post serializers so it stays internal; reading_time remains the existing public API field and is still computed at read time in this PR.
• Also strips the new columns from member activity-feed attribution and avoids leaking null reading_time into webhook payloads before population exists.
• Migration lives in 6.64/ (after v6.63.0); bumps Core + ember-admin to 6.64.0-rc.0.

No write-path population, backfill, or stored read path yet — those land in follow-up PRs.

Test plan

• Confirm migration adds both columns on MySQL (pnpm knex-migrator migrate for 6.64) and rolls back cleanly
• pnpm test:single test/unit/server/data/schema/integrity.test.js
• Spot-check Content/Admin post responses: no auto_excerpt key; reading_time / excerpt unchanged from today
• Migration review checklist on the PR

[github-actions]

It looks like this PR contains a migration 👀
Here's the checklist for reviewing migrations:

General requirements

• ⚠️ Tested performance on staging database servers, as performance on local machines is not comparable to a production environment
• Satisfies idempotency requirement (both up() and down())
• Does not reference models
• Filename is in the correct format (and correctly ordered)
• Targets the next minor version
• All code paths have appropriate log messages
• Uses the correct utils
• Contains a minimal changeset
• Does not mix DDL/DML operations

Schema changes

• Both schema change and related migration have been implemented
• For index changes: has been performance tested for large tables
• For new tables/columns: fields use the appropriate predefined field lengths
• For new tables/columns: field names follow the appropriate conventions
• Does not drop a non-alpha table outside of a major version

Data changes

• Mass updates/inserts are batched appropriately
• Does not loop over large tables/datasets
• Defends against missing or invalid data
• For settings updates: follows the appropriate guidelines

Walkthrough

The posts schema adds nullable auto_excerpt and reading_time columns through a new migration. The schema integrity hash and package versions are updated. Post serializers remove internal metadata from output, including raw reading_time values when no computed value exists. Member signup and donation event serialization also removes both fields. Tests cover the schema hash and null reading_time behavior.

Suggested reviewers: acburdine, 9larsons

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to d3e9f

This change adds nullable post metadata columns while keeping internal values out of public responses, webhooks, and member event attribution. The migration and serialization behavior are aligned, with no remaining concrete merge-blocking risk.
