fix(effect-sdk): cap the effect peer below rc.118

[JeremyFunk]

Effect 4.0.0-rc.118 removed the effect/unstable/{http,observability} paths the SDK imports. The open-ended peer (>=4.0.0-rc.113) let installs succeed and then fail with ERR_MODULE_NOT_FOUND at import.

• Peer effect → >=4.0.0-rc.113 <4.0.0-rc.118, so package managers flag rc.118 at install time
• bun.lock updated for the peer change

The SDK stays on the same Effect version as the monorepo, which can't move to rc.118 until alchemy (beta.79) and @maple-dev/effect-clickhouse stop importing effect/unstable/*. Supersedes #1175.

After merge: publish 0.9.0. The published 0.8.2 calls Config.string/Config.redacted, which no longer exist from rc.113 on, so no working release is on npm today.

Maple review

🟢 Confidence 5/5 · safe to merge
One-line peer bound plus its lockfile mirror; the range admits exactly the Effect pre-releases the SDK still supports.
_{quality 100/100 · no findings · tests not needed · risk low}

Caps the @maple-dev/effect-sdk effect peer at >=4.0.0-rc.113 <4.0.0-rc.118 so rc.118 installs fail at resolve time instead of ERR_MODULE_NOT_FOUND at import, and mirrors it in bun.lock. Config-only, safe to merge.

• effect peer of @maple-dev/effect-sdk now bounded below 4.0.0-rc.118
• bun.lock peer entry updated to match

What was checked

• Peer range keeps the workspace on the cabal effect 4.0.0-rc.117, which satisfies both comparators (root package.json:92-100)
• The two prerelease comparators make rc.113-rc.117 satisfy the range and rc.118 fail, so the bound does what the title claims
• All in-repo consumers of the SDK use effect: catalog:effect, so no workspace package breaks on the tighter peer
