build: bump version to 2.115.0

[dannimad]

Description

Bumps main from 2.114.0 to 2.115.0, the next development version after the 2.114.0 release branch cut. Includes packageVersion.ts regeneration and compat workspace version refresh (no compat-workspace package.json changes needed this cycle).

Part of the 2.114.0 release prep sequence:

1. Tag untagged asserts (build: tag untagged asserts for 2.114.0 release #27822)
2. Update compat generation (no changes needed this cycle)
3. Generate release notes/changelogs (build: generate release notes and changelogs for 2.114.0 #27823)
4. Bump main to 2.115.0 (this PR)

This PR must merge LAST, after the other two are merged.

• API Compatibility — breaking changes, release tags, type design
• Performance — algorithmic regressions, memory leaks
• Testing — coverage gaps, hollow tests
